Rotating bezel makes it easy to record compass readings Tough Solar charging system maintains advanced functionality while on the go. Get out and explore with more gentle footprints. * Biomass plastic is a polymer that is chemically or biologically synthesized from plant and other renewable organic substances, which is widely thought to reduce environmental impact and promote transition to circulating economy

Review: This is a very nice watch with a lot of nice features. I really like the compass directions overlay.
Review: 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!!

**Q: Does it have a step counter?**

**Q: Does it really gain 2 seconds a week??? That would make this watch trash ....**
A: Mine hasn't! Keeps accurate time.

**Q: Dose time update when you travel?**
A: No. You have to physically update time or date if traveling across different time zones or cross international date line.

**Q: What actually is Tough Solar  ?does Tough solar have a battery ?**
A: Yes there is a battery that is rechargeable. It is recharged by the solar cell so you never have to replace it.  As long as the watch sees some light once in a while it will keep running without having to worry about changing a battery

### ⭐⭐⭐⭐⭐ Review
*by G***I on August 29, 2025*

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.
