The band can be adjusted down to a wrist that measures 5.75 inches around. It looks a little odd adjusted all the way to its smallest size so if the kid has some meat on him and not too slender (like I was) it will be fine and he'll grow into it. It's an X-large watch face so if the child is quite slim this watch will just make it more aesthetically obvious as it hangs off the little guy. **Q: How do you adjust the Analog hands? I dont see a dial for them.** A: You can calibrate the watch hands by holding adjust button until the 2nd beep. Once engaged, make sure both hands are exactly at the 12 o’ clock position, then press adjust again to return to the time screen. **Q: the advertising says the band is black but the pictures show the band being another color. which is it?** A: The band on the one that I bought is black. Same color as the face. **Q: What is the difference between an Xl and regular sized G-shock watch?** A: Honestly, I don't think there was a difference. I bought this and it turned out to be the same size as the other men's G-Shock watch.. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Looking Watch *by on Reviewed in the United Kingdom 23 December 2022* If you like Camo watches you’ll love this. After trying & failing to get this watch because of fakes sold on eBay I finally got it & the real thing is a beauty. It’s a good size & feels comfortable to wear. Easy to read the time too. The negative display may not be to some people’s taste but I can read it so I like it. ### ⭐⭐⭐⭐ Poor light *by on Reviewed in the United Kingdom 11 August 2025* Difficult to see the dial clearly and light is poor but I am colour blind so maybe just me ### ⭐⭐⭐⭐⭐ Very good indeed *by on Reviewed in the United Kingdom 15 August 2022* Very good indeed ## Frequently Bought Together - Casio Sport Watch GA-100C-1A3CR - VARTA Batteries Electronics CR1220 Lithium button cell battery 1-pack, Button cells in original blister pack of 1 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/89457712-casio-mens-ga-100-xl-series-g-shock-quartz-200m](https://www.desertcart.jp/products/89457712-casio-mens-ga-100-xl-series-g-shock-quartz-200m) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-22*
