Description

Three new color variations of the Tough Solar GAS-100 add new flavor to this case design. Variations on a basic black design are created by three different bezels. The GAS- 100 comes with a stainless steel bezel for a standard design that goes well with a wide range of fashion styles. The GAS-100B has a black aluminum bezel for a cool design. A CASIO original molding process is used to produce deposition coated hour markers that combine with the metal bezels to create a look of elegance.

    • Awesome watch

This is the second time I have purchased this watch. It’s that good. The first time I bought it in a retail store in a mall called JC Penney. I gave that watch to a friend. I just re-purchased it for myself here on Amazon. I could not be happier! One concern about purchasing watches on Amazon is that you don’t know if you’re getting a genuine or a counterfeit watch. This goes for all watch brands, not just G-Shock. After receiving this watch, I was able to determine that — not only is it a 100% genuine Casio G-Shock — but also, it was manufactured in June 2024. I purchased it in October 2024 — only four months later. So the watch is also extremely new. The coolest thing about this watch is that in spite of its relatively large size, it is extremely lightweight and extremely comfortable. I own a bunch of other watches of various types, and 9 times out of 10 whenever I leave the house, I put this white G-Shock on. Another thing I love about it is that it is bright white in color. Not off-white. For the price, I could not ask for more from a watch. If you’re hesitant about buying it, pull the trigger. You won’t be sorry. ... show more

    • great durable watch for the cost
something i reallike is that it auto sets the time based on the time zone you select in the menu. also the stylish face design is pretty easy to read, along with the white band that adds nice contrast. the white led face light is way better on this model than others and does a great job illuminating the whole face. i couldnt figure out why the light was randomly coming on multiple times a day but later i discovered after a few uses that it senses when you rotate your wrist up to look at the face and turns the light on for 2 seconds, a pretty cool feature. ... show more

Comically huge but feels like a cheap plastic watch. Well equipped but just get a square instead. 5600 is half the price and feels nicer.
