Deal | Casio G-Shock watch with 7-year battery life hits record low price on Amazon after huge 45% discount

Some watches try to impress with smart features, touchscreens, or solar panels. This one doesn’t. The Casio G-Shock GD100-1B has been around since 2010, and it’s still doing exactly what it was built to do - take a beating, tell the time, and never complain. And right now, it’s doing that at its lowest price ever: just $54.03 on Amazon.

If this watch sounds familiar, it’s because we covered a similar deal just last month when it dropped to $60.98 - already a good bargain. But this new drop undercuts that, beating even the long-standing all-time low of $54.49 (as per camelcamelcamel) and officially setting a new price floor, even if it's by merely 46 cents.

The GD100-1B is a no-frills G-Shock that’s become a go-to for military users, athletes, and anyone who wants something dependable. It comes bundled with 200-meter water resistance, shock resistance, and a 7-year battery on a single CR2025 cell. The display is simple but functional, with a bright LED backlight, dual time, stopwatch, countdown timer, world time, and five alarms. No Bluetooth, no solar charging - just old-school G-Shock DNA in a bulky matte resin case.

Despite being 14 years old, the model still holds a 4.7-star average rating from over 1,700 buyers. It’s not flashy, but it does what it’s supposed to, and it keeps doing it for years. If you’ve been waiting for the right time to grab one, this is about as close to a “buy now” signal as it gets.

Buy the Casio G-Shock GD100-1B on Amazon.
