Best work/outdoors watch.
Perfect everyday watch! This is my second one, I hand the last one for 12 years countless deployments and travel. Held up great. very durable and reliable watch. Great value when you get it in sale. Size fits just right in my wrist which is about average size.

Very Accurate
I bought the titanium band version as I prefer metal bands when available for longer life and greater comfort in high summer temperatures. They are subject to scratching but as a retiree I am easy on watches. My sample remains within 1 second of my atomic clock after 2+ weeks of wear so excellent accuracy. No real need for Multi Band 6 radio synchronization with this accuracy level though I do have watches with that feature. The triple sensor provides more features than I need and I like the sunrise/sunset calculation capability. Solar charging is also great. Overall a excellent light weight outdoors man's watch. Currently, and when I bought it, the Titanium band version is a best buy as Amazon has it for the same price as the resin band versions. Per the listed MSRP the titanium band version is normally a $50 cost premium. To me the titanium band version is a much dressier looking watch and titanium does not wear out like resin bands do.

Solid watch with amazing features!
Excellent watch. The titanium band was easy to adjust with the included tool. Auto on light is one of the features I use every day and at night. Sensors are very accurate. I need the compass and use it indoors to orient for reports. The world time is something I'm familiar with and it's quick to change when traveling.

Muy ligero, elegante y con excelentes sensores
Acaba de llegar y me parece un reloj muy bonito. Lo que más me sorprendió fue lo ligero que es, tanto por la caja como por el brazalete de titanio. Tiene todas las funciones de los sensores y, comparándolo con mi Garmin, las mediciones me han parecido muy precisas. Estoy muy satisfecho con la compra. Personalmente prefiero relojes más grandes y robustos, especialmente los G-Shock, pero este tiene un estilo diferente. Por el brazalete de titanio, a simple vista tiene una apariencia más casual y elegante, por lo que creo que quedará muy bien con ropa semiformal y camisa. Sin embargo, cuando se conocen sus funciones, queda claro que es un reloj pensado para montaña y actividades al aire libre. Tiene brújula, altímetro, barómetro y termómetro, además de carga solar y resistencia al agua de 100 metros. Soy fan de Casio y me gusta mucho este reloj. Aunque debo admitir que mi Garmin me parece superior en conjunto, tampoco son relojes de la misma gama ni están diseñados exactamente para lo mismo. Muy satisfecho con la compra.

Cheap band!
Works the same as an old Suunto I have. Very light, feels good on wrist. The only downside is the metal band. It is not secure, comes off if your cuff catches the release buttons. I replaced it with a better band and that solved it.

Reloj excelente, su durabilidad literalmente es para toda la vida
Excelente Reloj digital convencional, las correas metálicas son resistentes y muy livianas, hace años tuve un modelo de Protrek más antiguo, y duro mucho más de lo hubiera pensado, también tengo un Gshock desde hace 20 años y todavía funciona, está línea de Protrek y la Gshock son excelentes.

Feature Packed. High Value for the Price!
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.

Lightweight
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 reliable wrist watch.
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.

Casio Pro Trek
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!!

Orologio casio
Il prodotto è buono ma dalle caratteristiche meccaniche inferiori alla serie precedente, cassa in resina anziché in acciaio, non ha il sincronismo radio cosa utilissima che il modello precedente aveva , Linea sportiva giustamente , mentre il precedente modello si accettava bene anche come orologio tradizionale non sportivo. Complessivamente soddisfatto ma intravvedo una perdita di robustezza.
