    • Solid watch
Color: Black
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!
Color: Black
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.
Color: Black
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

    • Casio GG 100-B-1B Watch

I love this Casio watch ! It has many functions, and looks bad ass ! With easy to read hands for time, and day/date, and for once a watch with a brighter light !!

    • All the features possible, and a connected app too
Color: Black
I had an old Casio Triple Sensor watch that finally gave up the ghost after almost 20 years. I replaced it with this G Shock Mudmaster and I love it. If you don’t like the low profile gray on black display, get one with the white numbers. The only thing that I don’t like is that it has a unique band attachment so no aftermarket watchbands work - including my Leatherman Tread. I am waiting on the connectors. ... show more
