CasioPRG340 Series | Pro Trek | 100 Meter Water Resistance | Compass | Alt/Baro-Thermo | Tough Solar Power | 1-100 SEC Stopwatch | Countdown Timer | World Time

This watch was a replacement for my 12 year old Casio Pro Trek PRW 3500. The new watch is lighter, thinner and the buttons are easier to activate. I love the rugged and functional looks of this watch. Also, unlike the Apple Watch, you don't need to worry about recharging the battery, it's solar powered. A big plus if you plan to be somewhere that does not have access to electrical outlets. The only thing missing in this watch vs. the 3500 is atomic auto timing. But with the watch being +/- 15 seconds per month that is no big deal.

Always love a good Casio Watch! I've used these for many years and they are durable, water resistant and easy to read.

I bought the PRG340 to replace my old SGW300H (battery powered with dual sensor barometer/altimeter and temperature) that failed after several years. It served me well as a rugged watch and one that was useful on mountain hikes. That watch was only $35-$40! I didn't see a newer Casio model like it, so I started considering any watch type. I ruled out an Android watch and other smart watches as I do not want to deal with recharging my watch frequently. I considered the Garmin Instinct Solar which looks even better in looks and features than this Casio, but reviews revealed that the battery fails to hold it's charge after about two years. That Instinct cannot be powered by solar alone. So it came down to the Casio PRG 270 and this 340. For $40 more, the 340 provides me a better looking watch for my taste, the dual level screen for the compass marks over the numerical watch face, and the rotating bezel for compass work. Other than that the features are the same, so get the 270 if you like its looks better and don't care about the enhanced compass features. Check out detailed reviews and the Casio instructions online for the cool trek mode and its capture of max/min elevation, total ascent/descent, waymark readings, etc. As someone else said, it's a great dumb watch.

Excellent all the way around.

Super light weight very nice watch a little hard to understand how to adjust the time etc

I searched and did not find another adventure oriented watch on the market with this many features at this price point ($168 as of this writing). Similar watches were found for $300+, and most of them aren't titanium! I was surprised to find that the titanium band also has a quick release feature (for switching out the band) along with an easy to use sizing tool to remove/add links. The key feature of the watch - triple sensor - did not disappoint. Each of the triple sensor features were calibrated and functioned well right out of the box. And all of the watch modes are easy to access and very intuitive along with being very readable on each screen. As for the solar charging, the watch was already charged (to Medium charge level), but was easily topped off to max charge after only a short (2hr) time next to a sunlit window. However, its worth noting that regular lamplight did not seem to be efficient at charging the watch. The only downside is that the watch arrived with packaging that was already opened. But, everything was intact and I chalk that up to the Amazon delivery driver and nothing to do with Casio. Bottom line - you can't go wrong with this watch. Being former military, I will say that its a great watch for that context as well as for weekend warriors, hikers, outdoor enthusiast, and anyone who needs a highly capable watch that has life sustaining/supportive functions.

I love this Casio!!! It’s light and tough at the same time!!

I love this watch! Durable, screen is scratch resistant and functional. Highly recommend
