Whats the differance?** A: It's good to 200 Meters. The term water resistant is used for legal reasons as no watch is impervious to water (few things are) so the term resistant covers their whatever. **Q: How long does battery last and is it replaceable. My old one tried to replace it but didnt work** A: My watch is over 4 years old and takes a lot of abuse outdoors...the battery has held up VERY well! Supposedly its a 10yr battery life?? Check at the manufacturers site for proper specs. **Q: Does it show the time digitaly** A: Yes, it has a setting where instead of the date it will show the time. You switch between the two by pressing the bottom right-hand side button. **Q: Does watch have a backlight? Looks very dark** A: no it is very dark - there is an led at the bottom you can turn on but it does not light up the face well. My son really likes the watch but says it is very dark and that does make it hard to read at night ## Customer Reviews ### ⭐⭐⭐⭐⭐ very good product great quality recommend 👍🏻 *by A***ー on March 25, 2020* very good product great quality recommend 👍🏻 ### ⭐⭐⭐⭐ Review *by 弘***弘 on October 2, 2019* 色使いは良いです！ ライトがちょっと暗めです。 ### ⭐⭐⭐⭐⭐ Review *by R***A on October 13, 2024* 見た目で大きいかなと思いましたが、子どもは気に入り、つけてみると大きさも特に気にならず、見やすくていい時計だと言っています。 ## Frequently Bought Together - Casio G-Shock Watch For Men Ana-Digi Dial Resin Band - GA-100-1A2 - Casio Watch For Men Quartz, Analog-Digital Display - Casio G-Shock Analog-Digital World Time Watch --- ## 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.tn/products/729454383-watches-g-shock-ga-100-1a2-overseas-model-reimport](https://www.desertcart.tn/products/729454383-watches-g-shock-ga-100-1a2-overseas-model-reimport) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-21*
