DESCRIPTION

You need a watch that can handle long shifts, daily wear and unpredictable conditions, without slowing you down or needing constant attention.

The G-SHOCK GBM-2100 is built for exactly that. Shock-resistant construction protects against impact, while a slim, low-profile design keeps it comfortable on your wrist all day.

With Tough Solar power, it charges from light, so you’re not constantly replacing batteries. Bluetooth connectivity keeps your time accurate automatically, without manual adjustment.

A stainless steel bezel adds a more refined, durable finish, while 200m water resistance means rain, washing or full submersion isn’t something you need to think about.

Every G-Shock has a way to read the time in the dark

Most watches aren’t built for Duty.

G-SHOCK is built to take impact, handle pressure, and keep performing when it matters.

Set it once.
It stays right.

Solar-powered timekeeping with Bluetooth keeps your watch accurate without the hassle.

It charges from light, so you are not constantly replacing batteries. Bluetooth syncs with your phone to automatically adjust the time, so you never need to set it yourself.

Reliable, low-maintenance, and built for everyday use.

A classic design, upgraded

The iconic octagonal shape returns with a refined stainless steel bezel, finished with a combination of brushed and polished surfaces.

Underneath, a reinforced inner case protects the module from impact, combining strength with a more premium feel.

Built to handle daily wear, while looking sharp enough for any setting

Built for reliability in demanding conditions, the G-SHOCK GBM-2100 combines a shock resistant structure with modern functionality and a slim, low-profile design that works just as well day to day as it does on shift.

Tough Solar technology allows the watch to charge from light, helping reduce the need for battery changes over time. Bluetooth connectivity ensures the time stays accurate by syncing automatically, removing the need for manual adjustment.

A high-contrast dial, supported by LED illumination, provides clear visibility in both bright and low-light environments, so you can check the time quickly in any situation.

Designed with practical use in mind, it is well suited to roles where reliability matters, including police, security, and other demanding environments.

Why police choose g-shock

You need gear that works without thinking about it.

G-Shock watches are trusted by officers because they are built to handle impact, long shifts and unpredictable conditions. Shock resistant construction protects against knocks on duty, while 200m water resistance means rain, washing or full submersion is never a concern.

With long battery life or solar charging, you are not dealing with constant maintenance. Clear displays and backlighting make it easy to check the time instantly, even in low light or high-pressure situations.

It is simple. It works. It lasts.
