The Casio ProTrek PRW61 is bit more eco-friendly


For one cause or one other, we have a tendency not to consider the affect of what it takes to fabricate these watches that we admire and acquire. For a mechanical motion in a metal case, the argument that they’ll final ceaselessly (and could be recycled as soon as they break) makes some sense. But what about these quartz-driven watches that stay in plastic instances? Those could be performed higher as effectively, which the Casio ProTrek PRW61 demonstrates.

How does it try this? Well, the Casio ProTrek PRW61 is the primary ProTrek to function a case fabricated from a bioplastic. What this implies is that reasonably than being absolutely petroleum-based, it’s counting on castor seeds and corn (amongst different supplies), lowering the useful resource affect. Oh, and it’s not simply the case – the caseback and strap are additionally fabricated from the fabric. How’s the longevity of the fabric? Well, that’s one thing that solely time will inform.

Once you get previous the brand new eco-friendly materials, the Casio ProTrek PRW61 is a ProTrek that we’re all fairly aware of. Along with the complete complement of quartz watch options (alarms, timers, world time) and outdoors-oriented functionality (temperature, barometer, altimeter, and compass), you’ve obtained that oh-so-lovely Tough Solar inbuilt. Meaning, this watch attracts its energy from the solar, reasonably than a disposable coin cell. How lengthy will that capacitor work? Quite some time, if my 14 year-old photo voltaic G-Shock is any indication.

Also like that previous G-Shock of mine, the Casio ProTrek PRW61 can sync its time to the atomic clock radio alerts being broadcast world wide. This means the watch will at all times have the appropriate date and time. The mixture of atomic sync and solar energy is one I’ve at all times favored, and I believe makes for a really stable outdoors-oriented watch.

I additionally like how the Casio ProTrek PRW61 has actually made it simpler to learn (and use) than my older G-Shock. The 51mm case has a big dial, with generously sized indices and fingers. Also, reasonably than having to rely solely on small subdials to determine what you’re doing with the watch, there’s a small digital show, which goes to be a giant assist to any homeowners of the watch.

The Casio ProTrek PRW61 was launched final month, and is out there proper now for $420. If you’re on the lookout for an outside watch that may sustain with no matter you’re doing, that is undoubtedly a stable choice. Perhaps not as strong of safety as a G-Shock, however you get quite a lot of outdoors-oriented performance in a ProTrek that’s exhausting to argue with. protrek.casio.com
