Casio PRG340 Series | Pro Trek | 100 Meter Water Resistance | Compass | Alt/Baro-Thermo | Tough Solar Power | 1-100 SEC Stopwatch | Countdown Timer | World Time

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!!

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.

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.

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, Amazon had an unusually good price, which often is not the case.

I will update this review when I receive my replacement, but for now I wanted to add my experience to the many others who received the wrong colored watch. Casio really should address this issue, as doing so might lead to the removal of the nasty warning from Amazon (front and center on the product page) that this is a frequently returned product. Also, the little cloth sack the watch is sent in is cute, but leads to fuzzy-covered unboxing photos like the attached. EDIT: I did eventually receive the correct item, and it is now my overall favorite watch. It is nearly two years old and still looks great, despite all the whacks it's taken on door knobs and other protrusions, as is common for big body watches. I have never seen another watch that looks like this one; it is truly original. It looks like a tool of vast capability, and it is. The compass is fast and accurate, and it's fun to climb a mountain and watch the altimeter go up and down. One time while hiking in the Adirondacks I became separated from my partner and this watch actually helped me retrace my steps and find them. The strap is very comfortable and I hardly notice the lightweight unit on my wrist unless I need it. The solar power is the icing on the cake. Casio knocked this one way out of the park.

The best watch I have owned. And it needs no batteries ever

The watch seems good and in like be condition as promised, I just unboxed it and have fine though so the features except I can't find the temperature gauge but that is me not the watch. I am happy with the delivery time, however I am upset that it was delivered at 5pm and they didn't bother to ring the doorbell as instructed it day there for over 3hts. I am handicapped and don't open the don't open the front door often. If it wasn't for me checking UPS I would have never known it was delivered.

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.
