    I have owned similar models going back to 1994 with each sensor version. I am both a weather fanatic as well as a tech geek. I had moved away from the Casio lines in favor of my Citizen Eco-Drive Skyhawk AT last year but now that I have received this watch a few weeks ago I find I am wearing this more than 50% of the time. I still love my Eco-Drive and it remains my favorite of my well over 25 watch collection mainly due to its true “all-occasion” appearance (anything from beach to formal wear). This PRG-270 has now taken place as my general wear go-to watch and living in the southeastern U.S. I find having the weather related features to be valuable as we head further into spring.I previously had the v.2 PAW-1300 ABC Pathfinder version which had been a favorite for several years until the solar rechargeable battery started to lose a bit of its storage capability after about 6 years of regular wear. It wasn’t abused or subjected to rough usage but it did get its share of bumps and bangs that occur during everyday use. I frequently used it for swimming in both the ocean and in pools and it also was exposed to water from hand washing and occasional watch cleaning (either thorough fresh water rinses or washing using mild dish detergent and water) and I never had any problems with water or moisture getting inside the case. Even living in a very humid region and exposure to harsh sun intensity didn’t seem to affect the watch. Prior to that I had one of the first v.1 models that I wore for several years without any problems until the battery finally died (that model was not solar like my PAW-1300 and the current PRG-270).What makes this watch such a bargain is the fact that it includes the highly acclaimed v.3 sensor while keeping the ABC + thermo features as well as the Tough Solar option (I will only buy either solar digitals or automatic analogs because opening the case back either compromises the water resistance or requires an expensive battery replacement that also requires a replacement of the gasket/ring that creates the seal.). What makes this watch even better in addition to the improved sensor is the ability to manually set your home location (lat/long coordinates) which makes the sunrise/sunset data accurate. The only thing this watch is really missing is atomic time synchronization. For the price of this watch I can live without it and wouldn’t expect that it would be included given all of the other features included. I synchronized the time on my PRG-270 to my Eco-Drive which does have atomic synchronization and after about three weeks it’s still within about two seconds so this watch so far appears to keep very accurate time (with the exception of very specific specialized usage I would think that is more than accurate enough for almost all users and is more accurate than even high-end automatic analogs like Rolex and Breitling). This watch is on the large size for its case size but not excessively so that most wearers would not find it awkward or goofy looking. It is also fairly light for a watch of its size and the band size & length are appropriate for its size and the average person.If atomic synchronization is a must then look at the ProTrek 3000 line and be prepared to spend about $100 more. If you can live without that feature then this is the watch you want if looking for an ABC watch with current sensor technology and solar power. Casio has a well established track record manufacturing these types of watches and a history of reliability and durability as well as continually developing and implementing improved technology over time. I would not hesitate to recommend this watch to anyone.Just a side note – Most of the negative reviews I have read for this watch and similar other models appeared to be related to that user either not reading the manual and performing the initial setup properly or having unrealistic expectations from this watch. Please do not let them influence your decision to buy or not buy this model. If you do buy then be prepared to spend about 30 minutes or so to properly setup and calibrate the watch using accurate data for your location. Calibrate the temperature with the watch off your wrist at least 20-30 minutes to a known local and accurate thermometer. Do the same with the barometric pressure to a current accurate local reading. Location coordinates and altitude can be obtained easily from a GPS device or online sources (Wikipedia will work for those without access to GPS data or do not know where to obtain that information online.). Once you have accurate information entered I think you will find this watch to be valuable and enjoyable. If using the altitude feature for hiking/climbing you will need to calibrate the altimeter to a known reference at the beginning of your trek and if the weather/barometric pressure is volatile at the time then additional calibration to known reference points may be needed if on an extended trek. That would apply to even the most expensive ABC models so that is not a deficiency of this particular model.

    I love these watches. I also have the PRG-270D-7CR version which looks a little classier for the office, and recently added the GW-9400-1CR model which is actually so nice that I’ll probably only use it when hiking and cycling. So I got this PRG-270-1 model for everyday use and as kind of a “beater” so I won’t get miffed if it gets scratched, etc. These watches are great. I especially like the barometer for tracking weather trends, and the pressure alert works very well: if you know a storm is on the way soon or you see the barometer trending up or down, you can use the alerts to let you know when sudden or critical changes are occurring. You have to take the watch off for 20 mins for accurate temperature readings, but I understand the limitations of the technology. The altimeter works ok, as does the compass. For most of these features it’s necessary to calibrate them before any real use. But this technology is as good as it gets unless you jump up to a GPS watch, and those are quite expensive, often have software bugs, require regular updates, and include an array of functions often more complex than they’re worth. I’ve had the Samsung Galaxy Neo 2 and the Gear S smartwatches, and after a few months was left underwhelmed by their performance once the novelty wore off. You’ll pay hundreds of dollars for one and within 18 months it’ll be outdated and replaced by a “newer, better” model. No thanks. I’d rather have one of these Casio’s that give me only the info I really need at a glance, and don’t require daily recharging (downtime). They may not be “cutting edge technology”, but they perform without any hassles and are far less expensive. I’m done with so-called “smart” watches. I prefer “useful” watches. YMMVCons:-I wish these watches had atomic timekeeping. They keep accurate time, but you have to manually adjust Daylight Savings Time and changes in time zone. However, atomic timekeeping models do cost more.-The end of the watch band is nearly impossible to get through the retainer loop when taking the watch off, so much so, that I’m concerned the band might break from the amount of force required.-I wish the snooze alarm had the ability to select the days of the week you wanted it to sound, such as M-F.-I wish Casio would realize that the top button should be FORWARD and the bottom button should be REVERSE. They have this backwards on all of their ABC watches, and others as well.Otherwise these watches are fabulous. Highly recommended!

    I bought this as an exact replacement for my old watch. Replacement bands are expensive. For me it was worth it to just replace it. I have to charge the old one more often now and the band is cracking in 3 different places. It’s been through a lot between different environments, exposure to chemicals and taking a physical beating. It is a bit bulky, so you may need to remove it to get your arm in tight spaces. I don’t use the compass/altimeter/barometer enough to speak on the accuracy of each. I used to check the barometric pressure when I’d get a migraine. I bought it for the multiple alarms/snooze, dual time/zones, backlight (makes a great low light flash light) and ruggedness. I sleep a lot better when I have an early flight and I can have 3 alarms set, plus a snooze. Hard to hear the alarm if you arm is under your pillow (set it on a nightstand or other). Dual time zones makes it easier to keep track of time when your in multiple zones. Temperature is fairly accurate if you take it off your wrist and let it sit awhile. If we were in a creek or lake, I’d let it sit in the water and check the temperature. It’s been a long time, but I used to take it to the community pool with my son and we’d toss it into the different depths to see what it would read. I had the old one for probably 4 years and it still works. I had a problem with the original where you had to tilt at an angle to see the screen. I considered it my privacy glass. No one could look and tell the time with out me angling it for them (funny to me). This one is clear as can be. It arrived on medium charge and is working fine. I don’t know how well it charges under office lights, as the old one would never return to full unless I left it on the dash of my truck to charge in direct sun light. I wear short sleeves year round, but the only way to charge it back to full is about 8 hours of full sun . That would keep it on high for a few months, maybe 3. As it got older I might leave it out there 2 days in a row (about 16 hours). I haven’t been able to leave the new one outside as we haven’t had direct sun in the last 5 days. Yay New York!

    Firstly, excuse my poor english, it’s not my native language.I originally wanted a G-shock. Till last I realized that my soul coveted not a G-Shock, but a Protrek watch. I ordered one from amazon (was delivered very rapidely, less than 3 days) and waited more than 1 month a friend of mine to bring it to me in my country (Romania) from USA. It’s a good looking, awesome watch, simply I love it! The build is OK, seems solid and tough, the plastic don’t give the feeling of cheap. It feels very good on wrist, comfortable and light, despite its size. It’s a big watch, but even at my thin wrist (despite my 188 cm height) looks very, very good. Very intuitive, I didn’t need to read the manual for settings. The only part I will read in manual is the calibration of sensors.I don’t regret at all my choice, because (in my opinion) G-Shocks under 150-200$ are ugly and poor in features.

    This is my third ABC watch; I also have the original ‘Pathfinder’ and a Suunto Vector. Here’s a few reasons why which might help you make your decision to buy this:- This watch is just the right size; big enough to operate with heavy winter gloves but not comically large.- The response time from button push to readout is very quick with this third generation sensor, about a second.- Unlike my other ABCs, I’m not concerned with draining the battery by taking frequent readings because this one is solar powered. – The battery life is estimated by Casio at 6 years, based on # of charging cycles and battery ‘memory’.- The auto-light which activates when I flick my wrist is nice for one handed viewing at night. I don’t find it too bright. User can select 1/5 or 3 seconds.- I like having the Sunrise/Sunset data one button push away (bottom right button while in time mode). I find myself checking it every few days to observe how that cycle is changing.- Like other ABCs, it shows pressure trends so basic forecasting can be done (assuming true altitude has been relatively constant)- The altimeter is more sensitive and precise than my other ABCs. Like some other reviewers have mentioned I can raise the watch and watch the altitude readout change by ONE meter, then back down again.The altimeter is ‘precise’, but to be ‘accurate’ you must tell it the current altitude before you start your climb. These watches interpolate altitude from a pressure/altitude lapse rate formula. The readout will track that ratio perfectly accurately, but that lapse rate (m/milibar) is only accurate in a NOAA ‘standard atmosphere’, which is a nominal average. Real world lapse rates vary and so will your indicated altitude for various reasons (which are all interesting to learn about). For example on a colder than standard day it will read high, and on a hotter than standard day it will read low.This watch IMO would be a great tool for a child or anyone who wants to studying many interesting subjects, lapse rates, adiabatic cooling, pressure effects on weather, and so on. Calibrating the altitude is simple, press the set button and increment the readout to your current known altitude. Having to tell an ABC watch the altitude is not absurd, and works as follows: on a recent climb of Fuji my group started from the station 5 bus terminal which we knew to be 2,300m. The summit is at 3776m and there are huts every few hundred meters of elevation. It was nice to know how ‘far’ until the next hut, especially the one we slept at, and then how far to the summit. A simple calculation using the altitude and time from the watch such as ‘the previous 100m took one hour’ gave a rough estimate of ETA; which helped to keep the group motivated.After years of using these watches, I wish Casio would incorporate one feature which I call ‘altitude lock’ or ‘base-camp lock’. If the user knows his/her true altitude will not change for several hours, he should be able to lock the altitude readout at its current value. Any attempt to use the altimeter would show “LOCK”. Then, when the climb resumed the next morning, the indicated altitude would NOT have drifted up or down due to weather changes over the past several hours; it would not be any less accurate than it was the moment the watch was locked. The new Suunto Core might have this. But one can’t have it all for about $100.For what I paid, $104.99, this watch is an incredible deal; especially since I won’t be spending valuable time and real money on batteries for several years.

    I’ve not written a product review in a while, but in response to some questionable negative reviews, I feel compelled to write this one. THIS IS AN EXCELLENT WATCH/TOOL! Don’t be misled by negative reviews by those who don’t understand how a watch like this works.First, as an aside really, forget about paying hundreds more for an atomic triple-sensor watch. I previously wore only atomic watches for years, but you don’t need one. This watch is accurate to a second or two per month. My son and I both have have this watch (I’ve had mine for 3+ years, he for 2+) and with the original battery (thanks to the solar function), both are as accurate as they were on day one.One who understands the limitations inherent in a watch like this will appreciate its function; those who do not understand leave a 1-star review.Altitude may be off hundreds of feet. This is normal, as the watch uses barometric pressure to calculate altitude, and local pressure changes constantly with the weather. When I drive through a mountain range and my altitude changes by thousands of feet, I get a good idea of my elevation — and a variance of a few hundred feet matters little. When I hike through mountains, I first calibrate my watch with the known altitude of my starting point to get precise altitude readings. But even if I fail to do this, the altitude changes the watch provides me are still accurate, so I know how many feet I’ve gained or lost hiking.As for temperature, of course I must remove the watch from any heat source (in this case, my arm) to get an accurate measure! I take off my watch and set it in the shade for an accurate temperature reading in 10-15 minutes. At least I’ve always got an accurate thermometer with me.I’m surprised nobody complained that the compass doesn’t work with the watch sitting atop a strong magnet.Learn to use the watch properly and enjoy a powerful tool strapped to your wrist. This really is a very good watch/altimeter/thermometer/compass.

    You can’t do much better than $100 for a solar powered ABC watch. I have owned the G Shock GW9400 Rangeman. The Rangeman is perhaps a little more durable and is water resistant up to 200 meters and has atomic timekeeping. The Casio Protrek PRG270 is not fragile, sporting some of the same shock resistant Casio technology, and it’s water resistant up to 100 meters (more than enough). This particular Protrek does not have atomic timekeeping, but that’s not a deal breaker for me.The biggest differences to me are the fit, function and legibility. Both watches are large at just over 50mm, but the Protrek is 3mm thinner and has a flatter profile. Protrek did not waste any space on the display with a lot of small windows like you see on most G Shocks. The display is simple, with large digits that are easy to read at a glance. The back light works better also in my opinion. There are three separate buttons for the ABC functions, making this watch easier and less of a hassle to use than the Rangeman with one button to toggle through all the ABC functions. The Rangeman also costs twice as much, even on the gray market.If you’re looking for a tough, readable watch with easy-to-use outdoor functions, this Protrek is a great choice.

    Casio got the features and price very well balanced on the PRG-270. This is a good performer, especially given its price.PROs:-ABC functions work very fast-Solar recharged means not worrying about the watch dying mid-use-Good light weight and comfortable designCONs:-no major concernsI have two other Protrek watches that are close to the PRG-270 in features, the PRG-300 and PRW-2500. The light weight makes it more comfortable than the -2500 and the size makes it slightly more stable on the wrist than the -300. Both the PRG-300 and 270 have very fast function speed, especially compared to the PRW-2500 which is slow and displays unnecessary graphics.While this does not have atomic timekeeping like the PRW-2500 or some other G-Shocks around this price range, I don’t think it takes away from good features of the PRG-270. If my only task is to adjust the watch 10 seconds every month because I lack atomic timekeeping, then I think the price difference is worth it.Now, compared to it’s sporty brother, the PRG-300, it seems like the features are the same. The display is great and functions are fast. The biggest difference between them is size and wear. This watch is bigger and seems to sit a little lower. The PRG-300 is smaller, rounder, and feels more like a sport watch. The wear and fashion are truly the only differentiating factors between the PRG-270 and -300 in my opinion. I like both of them a lot.White water rafting or hard use would be the only limiting factor that would make me suggest to you to consider the PRW-2500 since it has the 200m water resistance. If that’s not needed, than this watch is brilliant for its price and makes a great daily wear.

    This is the third watch I have owned in this series. The last one lasted over 10 years through 3 battery replacements. It’s still working except for the adjust button; I can’t adjust for daylight savings time. LOL Plus the watch band was the fabric one and was getting weathered and frayed. This new watch has the plastic band which I will replace with the fabric band soon. My first watch in this series had the plastic band and when it broke, I couldn’t find a replacement band so I got a new watch. Don’t get me wrong, the first watch band lasted a long time and the watch bands are now available. It’s just that the fabric band on the second watch lasted for the entire 10 + years I have had that watch. So fabric will replace the plastic band soon.Just remember that the sensors in this watch are ANALOG sensors and are subject to the ANALOG environment around it. If you are going to use it for hiking, traveling, or any kind of recreation, just remember to check and adjust the watch at known reference points often.As for the watch its self, I think it says all that I have to say about them, with this being my third one.

    I decided to put this review up as a few reviewers have issues with the accuracy of the altimeter readings, and may not understand the limitations of these watches:Design======The PRG270 is smaller than some of the older Protrek models, due to the smaller sensor, and they have moved the sensor location from the 10 o’clock to the 9 o’clock position. The triple sensor makes these watches sometimes called ABC watches as they have Altitude, Barometer & Compass readouts. The smaller design makes it easier to wear everyday, however the face is still relatively busy, with the case having front raised sections (at the 12, 3, 6 & 9) with indents. The sensor at the 9 o’clock position sits higher than the raised section at the 3 o’clock position. The crystal is recessed nicely as usual on Casio G-Shocks and Protreks.I wish the design could look more like the PRW3000, which is cleaner and more stylish IMHO 

    Casio Men’s PRW-3000-1ACR Protrek Digital Display Japanese Quartz Black Watch

    , but is also 3 times more expensive. The display is similar to the other Protreks, divided into three sections. The top section has a dotmatrix display and can show the date, or altitude/barometric graphs, the middle section is the time, and the lower section is the seconds.The watch is light, mine weighs about 67 grams (2.36 ounces), and has 10Bar water resistance, which means it is ok in a rain shower, or shallow swim, but it wouldn’t be ok with a scuba dive. I have only had this watch in the rain, and it functions fine.One issue with the PRG270 is the strap uses a 18mm spring lug, so if you wanted to put a wider Nato/Zulu strap, you’d need an adapter.Features=======- EL backlight, this is nice and bright, and the EL button is still on the front, they have moved the adjust button on older Protreks from the front to the 10 o’clock position. You can still set this for Automatic, and set it for 1 or 3 second display.- Date display – on the Time display, you can change date to Day&Date, or Month&Date, or Barometric Graph only (no date).- Setting time – this is a breeze. when you get the watch is preset to Tokyo time. Changing the Time zone to your location, and checking if Daylight Saving Time (DST) applies, and voila – the time is set and easy to change if you travel. The secondary timezone is set by picking various preset cities. I have not had any issue with the time accuracy so far.- Stopwatch/Countdown TImer (24 hours max)/Alarm – All standard, but the alarm lets you have 5 individual alarms, and the alarm is louder and longer than my Suunto Core watches.- Sunrise/Sunset – this is also a breeze to set. The PRG270 lets you input the longitude and latitude of your location for accurate sunrise/sunset times. Compared with my Suunto Core watches which only lets me choose nearest cities.- Power save – I have set this to on, and the watch will display will go off overnight, or after a period of unuse to conserve battery. You can wake it up by pressing any button.Altimeter/Barometer (This is from my previous reply comment to a review on the altimeter readings)=======All altimeter watches without GPS embedded will calculate the estimate of altitude by changes in air (barometric) pressure.Air pressure can change due to many things, like change in elevation, change in weather, your physical location and wind. So for example, if you get a low pressure system coming through over night, while you leave your watch on the table, it could appear that you have ascended a few hundred feet in your sleep. Similarly, if you take the watch on a commercial airplane, it will not give you a reading on the actual altitude, but a lower altitude, based on the pressure within the cabin. If you fly in an unpressurized aircraft, it will give you a more accurate altitude reading. I have taken a Suunto Core with me when I’ve been in a few prop aircraft, and used it as a secondary altimeter in skydiving, and it has been fairly accurate after calibration. I’ll take the Casio up next time and see how it goes.Also, I have found that the altimeter and barometer readings tend to vary with temperature, and gives marginally more accurate readings off the wrist especially if I have been hiking and my wrist is warm.I also have a few Suunto Core watches, and the Suunto Core is quite clever in the way it calculates the altitude. If you leave it in altitude logging, it will gain elevation as you physically climb up, as the barometric pressure changes faster than it does when the weather changes, so it realises you are climbing. But once you stop climbing for a while, it realises this and any slight air pressure changes it takes as weather change, and not altitude gain or loss. The Casio doesn’t have this feature.For accurate altimeter readings you still need to calibrate your altimeter watch to your reference altitude on a fairly regular basis. I do this when I want to log altitudes before a hike/climb. An easy way to do this is to check Google Earth which gives accurate altitude readings when you put your location. You can then calibrate the barometric pressure from your local meteorology service (I take mine from their website on the day I calibrate).If kept properly calibrated during a day that has fairly stable weather, they should prove to be very accurate overall. In varying weather conditions, you will see some variation. Again, it’s essential to know the reference altitude to get back on track.Still, this can vary, and the altimeter watch is not a scientific instrument, but only designed to give you an estimate on current altitude. For example, on a recent trek to Mt Everest Base Camp, I ran a few loggers, including a barometric altimeter, and on the return trek later in the day because I was exhausted, I didn’t recalibrate the altimeter at the known peak height, the altimeter log showed an altitude difference of about 10 metres (see here imgur.com/8XrW0iD)So if you are after an altimeter watch for accurate altitude readings at specific location, without daily calibration, the Casio PRG 270 it is not the right tool for you.The accuracy of the altimeter when properly calibrated is pretty close when I’ve compared it with my Suunto Core watches, Garmin handheld GPSs and altitude markers on trails. I usually the watch strapped to my backpack strap when hiking, so it doesn’t get thrown out by my body temperature.Also, I haven’t checked how fast the altimeter updates. It seems ok for hiking, but I haven’t taken readings and monitored it while bike riding for example. The newer V3 Sensor has reduced the time required to measure altitude from 5 seconds previously to 1 second now, and the altitude measurement unit has been improved from five metres to one metre.The temperature reading in the barometer was pretty accurate, but I’ve noticed it can get wierd with rapid changes in temperature. For example, if you have left the watch by the window to solar charge, the temperature will be wrong for about half an hour until the watch and sensor cools down, and you get a more accurate measurement. You should only calibrate the temperature when the watch has cooled to normal temperature, and I have done this with a high accuracy thermometer. The temperature reading it gives includes 1 decimal place. In my Suunto Core, it only displayed the nearest degree, but after calibration, both Suunto watches and the PRG270 are pretty accurate on temperature off wrist.Altimeter logs – the watch has enough memory to store 30 logs, and 14 trek logs, but I think the Suunto is better here as it can record more.Compass========As with all electronic compasses, it will get interferences from other magnetic sources, and may not be accurate on boats, planes, trains, or even in some buildings where the ferroconcrete magnetism causes inaccurate readings. That said, I have had good experiences with the compass, in those conditions. The magnetic compass can be set for magnetic declination, and you can still display the time in Compass mode. The top section can be set to display the bearing (0°-360°) or the direction (N,S,E,W, etc).You have to have the watch level with the ground to get an accurate compass reading, and it is easy to calibrate by holding the adjust button down. You should only calibrate when way from other magnetic sources. I do this when I’m starting a hike, away from the car, but always carry a real compass and maps if going out bush.If you leave it in compass mode it will stop the compass to save battery.Summary=======Overall, for the price, this is a very good triple sensor watch that because of the smaller size from previous Protreks you can use for everyday wear. If you understand the limitations of ABC watches (they are not intended as precision instruments), this is a great first ABC watch.
