This model can measure Altitude in 1m increments (previously 5m) and display compass readings with 60-seconds of continuous measurement (previously 20 seconds). In addition to the altimeter and digital compass, the watch's Barometer, incorporates a unique Barometric Pressure Tendency Alarm that alerts the wearer to sudden changes in pressure readings.Design features include a case designed for outdoor gear performance. Large side buttons and one-press access to digital compass, barometric pressure and altitude, and temperature readings keep important information at your fingertips. Other features include Tough Solar, 100-meter water resistance, and more. Everything about these models is designed and engineered to make them essential pieces of outdoor gear. Black resin band digital with neutral face. CasioWith the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward. P.when('A').execute(function(A) { A.on('a:expander:toggle_description:toggle:collapse', function(data) { window.scroll(0, data.expander.$expander[0].offsetTop-100); }); }); Designed to be a resilient, this high-performance timepiece offers Casio's one-touch Triple Sensor Technology and Tough Solar Power. The one-touch Triple Sensor Technology offers a pressure sensor for measuring barometric pressure and altitude, a thermo sensor for measuring temperature and a direction sensor for taking compass readings. The PRG70 allows users to switch their focus between time and compass measurements and is designed for adventure-seekers and lovers of the great outdoors. This model is a resilient high-performance timepiece that offers a variety of different features such as a digital compass, sunrise and sunset data, 4 daily alarms and 1 snooze, stopwatch, countdown timer, 12/24 hour formats and a power saving function.

Review: Great watch - My review is for the watch face and not the band, because I absolutely cannot stand the polymer wristbands on modern watches, this watch being no exception. Replaced with a canvas band and it's now the best and most comfortable watch I've ever owned. I needed a watch that was waterproof, shock resistant, and that had solar charging. This is the best watch I could find that has those features that was relatively affordable. The additional functions just seemed interesting and were a bonus to me. This review may not stand up for someone who uses this watch for adventuring, and personally I wouldn't want all those functions in a watch vs a dedicated tool if I was trying to accurately judge the weather, altitude, navigation, etc. The functions, as far as I can tell, are accurate. Barometer seems to line up with the weather patterns in my area though I'm not an expert on it and only have some light reading as reference as to what the readings actually mean. I don't climb enough mountains to say if the altimeter works, though it is accurate to the elevation of my home. Compass seems consistent and accurate, which is one of the only functions I actually use regularly, and granted I'm not doing land NAV so I only need a general sense of NSWE. I don't know if I would trust a digital compass for navigation unless it was getting location data from GPS or something but it's accurate enough to find your way back to a main road if you got turned around in the woods. More importantly to me, the time is very accurate. I've had it for several months and it is still accurate down to the second when I initially set it (compared to my phone's clock which gets updated daily). The solar charging works great. I haven't had to leave it exposed to sunlight to charge it like many people online recommend to do; it gets plenty of charge just from me wearing it and whatever ambient light is inside my house. I haven't gone more than a week without having it on outside so your mileage may vary, but I expect even sitting on a dresser is enough to keep it charged. Also something I didn't realize I needed but that comes in extremely handy is the automatic light mode. You just lift the watch to eye level and the light comes on. Working early morning shifts before the sun comes up it's really nice to see the time without having to press the button, which is especially difficult if you're wearing gloves. My only complaint is the learning curve of the buttons on this thing. The 3 buttons on the right side are labeled and the left 2 buttons are not. The left side is what gets me mixed up as it controls additional timer/stopwatch/alarm settings and cycles various data displays on the other modes. With some practice the left side buttons become easier to use but without referring to the manual I struggled for the first week or so remembering how to use half the timing functions on this watch. I still sometimes hold down the wrong button to get back to standard time mode and end up going into the programming mode. Not a big deal because you can just press it again to get out of it but when you're just trying to see the time it can be a little irritating. I think it also reverts back to the time mode after 30-60 seconds for whatever mode you're in so if you REALLY can't figure it out, it will eventually do it for you. If I used the other functions more often I'm sure I would get better with it so I think this is a use case for me, and not necessarily a typical user.
Review: Crazy amount of features--great watch. - What a nice watch. It has a ton of handy features--especially if you are a hiker. The time is very easy to see. My eyes aren't as good as they used to be, but the digits are easy to see. It is solar powered which I demand that all of my watches have. I typically prefer analog watches but this makes more sense as a digital because of the features. It has a barometric pressure gauge, altitude gauge, altitude tracking (min, max, etc), a compass, sunrise and sunset times, world time, a number of alarms, a snooze alarm, a stopwatch, and a countdown timer. The barometric pressure is surprisingly accurate on this. The altitude also works well but since barometric pressure affects altitude it will drift after a number of hours so you need to set it to the height of your location prior to setting off on a hike. It seem to be very accurate as well. Just going upstairs in my house shows a change in altitude. The compass works well too. You can set magnetic declination for it and also set a travel bearing. It is not nearly as accurate as a dedicated compass, but I think it is accurate to about 10 degrees which does give you your general direction of travel. It has a temperature sensor, but you need to take the watch off for a few minutes to get the current temperature. It does seem to be accurate. It is water resistant to 100 meters. This makes it okay for swimming and snorkeling (but not for diving). I wish it was good to 200 meters, but 100 meters is acceptable. If you set your latitude and longitude it will show the sunrise/sunset times at that location. You can also look back and forward for a few weeks to see what it will be on different days. The alarm volume could be better--it is a little too quiet. The backlight works very well. It has world time so that if you go on vacation you can set it your destination and display the current time there. It does not have atomic time. There is a new model that does have it, if you want it--I didn't want to spend that much but it is available. I can say that it is a pretty handy feature to have, but you really don't need it. It isn't the best looking watch, but it is very functional and has a ton of features. I really like it and have been wearing it more than my $600 Citizen (analog, solar, atomic time, world time, 200 meter water resistant).

## Questions & Answers

**Q: So many ProTrek models & prices!  What's the difference betw. PRG260 &270 and PAG80 &240?  Do they all have "Triple Sensor v3" & "Tough Solar"?  Thx.**
A: JC, I enjoy these watches,use them and have researched them. All the models you asked about feature the tough solar label. Only one of those watches you asked about has tough solar and version 3 sensor combined-the PRG 270. I know the 270 model,own it and use in the mountains of northern NH. I own older Protreks too. The version 3 sensor is nice and fast. It quickly updates my altitude changes. This may or may not be important to you. All these Protreks are darn good. Keith

**Q: Do you have to remove the watch to get an accurate temperature reading, like the SGW-100 I have?**
A: Try this: leave the watch on for a few hours, so that it gets used to your body temperature. While it is still on your wrist, adjust the temperature reading of the watch to match the air temperature of your surroundings. I think you will find that it will now accurately read the surrounding air temperature. I did this many months ago, and I have found that it is very accurate! So you don't have to remove the watch at all!!

**Q: The light on the watch comes on at night when I turn my wrist or move my hand is that normal?**
A: That is normal if you have the Auto EL backlight setting on. It is on when there is an "LT" shown in th bottom LHS of the screen.  It uses a tilt sensor to detect when the watch moves more than 40degrees to turn on the backlight.  If you want to turn off this function, hold down the Light button until the LT disappears from the display.

**Q: Does this watch store temperatures for 24 hours**
A: It stores altitude and barometric pressure, not temperature unfortunately...
