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.

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

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.

Amazing watch

A perfect titanium watch if you are looking for one. It’s combines Casio’s triple sensor in a lightweight and stylish case that is very comfortable on the wrist. The dual lcd display makes it easy to view the compass. All in an extremely affordable package

Great wrist watch light great display and the big thing about it is that it is solar powered. I have a G shock watch which is also excellent but when the battery runs out it can take up to three months to get a new battery installed. I live in rural NSW and last time it took just under three months to get it back from Sydney. So next time the battery goes flat then it's in the bin for the G shock.

La Montre est de l Bonne taille et solide

My last Casio Pro Trek is still working after !0 years though the LCD display is a bit dim. Casio service centre informed me that there is no spare parts anymore. Hence I grabbed this as soon as it was available for a discount. The sheer toughness encased in a biomass/titanium casement and bracelet ensures that it would last another 10 years! Good value for money!!

Es mi primer Casio Pro Trek, porque siempre he comprado G Shock, y la verdad está excelente, robusto, eficiente.
