Review: Love love love this watch - I've been wearing digital casios since 1981, most recently the G-shock series. However, the G-shock seemed oriented towards very high durability and a military look, which seemed unnecessary. Some of them had features on the face, for example graphic illustration of the passage of seconds or phases of the moon, that seemed decorative rather than useful. These resulted in cluttered faces. The Pro Trek is simple and functional. Date and time are very visible with a glance. Battery with solar replenishment (and a small charge status indicator), no USB charging. My phone will give me global positioning with a bigger format, no need to duplicate with a watch that will just be one more thing needing charging. One drawback is that some of the minor indicators on the face for settings are much too small, but these are ones that are typically set and not adjusted. I love the very visible compass feature (even though my phone does have one), useful in both urban and nature settings. The Pro Trek is fairly large but is more comfortable that my previous smaller G-shock. Sometimes things are just very pleasing, and this is the case for me with the Pro Trek. I've dropped and banged it a number of times and anticipate continued durability even if it's not a G-shock. BTW, desertcart had an unusually good price, which often is not the case.
Review: Really good stuff!!! - This model is a really nice upgrade from my previous Casio altimeter. Although the latter was (and is) great, this new model: - Has larger digits, so it's easier to read (especially for an old geezer like me!) - Has a dedicated, much larger light button that's no longer right next to the adjust button -- so it's MUCH easier to use in the dark! - Has a much brighter night light -- so it's MUCH easier to read at night - Has a really good, functional band (much better than the PITA one on my previous model) I'm VERY happy with it -- definitely 5 stars for this one!!

### ⭐⭐⭐⭐⭐ I bought the PRG340 instead of...
*by V***O on April 24, 2025*

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.
