    • Solid watch
Review Image by Jesse
The watch is solid & heavy-duty. Has a lot of options from barometer to compass. Easy to set up with the Casio app (g-shock app is ending soon). Very happy so far.

Amazing watch, very tough looking, lots of help functions. Black digital screen has a extra shinning contrast that makes it easy to read even in full bright sun. Black and white glooming arms are ready to read in the darkness. Recommended for al Gshock enthusiasts.

    • Works!
Why did you pick this product vs others?: My husband wears this daily but it definitely doesn’t stand up to concrete of course and welding obviously. It still does great though and he will definitely get another one! Fit him perfect, a chunky but works great!

    • It's the real deal.
Review Image by Some Guy
I had the Green and Yellow version of this watch before but ended up returning it because it just didn't wow me. But I just love this black out version. It's the real deal, G-Shock Mudmaster with step tracker. The carbon fiber core make it super light. The only down side is that it doesn't have solar charging. It's not a huge deal breaking for me cause I can just swap the battery out myself when the time comes. The battery will last for at least 2 years and I don't see myself going on a 2 year long field trip. Overall I love this watch with this color combo and I will recommand anyone to get it. ... show more
