Our take on the Casio G-Shock GM-2100

The GM-2100 is Casio's metal-bezel take on the classic square-shoulder G-Shock: an analog-digital watch with a stainless steel bezel, resin case and silicone band. It keeps the full G-Shock toolkit — 200 m water resistance, shock resistance, world time, 1/100-second stopwatch, five alarms and Super Illuminator LED light — in a slimmer 11.8 mm case than the chunky 2100-series originals. Reviewers like the dressier look and the analog hands, and most find it comfortable for daily wear. It costs more than a plain resin G-Shock and less than a full metal one, so it sits in the middle of the range.

Best forBuyers who want a G-Shock that looks dressier than resinEveryday wear with water and shock exposureTravelers who use world time and multiple alarmsPeople who prefer analog hands with digital functions
Pros
  • Stainless steel bezel gives a more premium look than all-resin G-Shocks
  • Slim 11.8 mm case wears flatter on the wrist
  • 200 m water resistance and shock-resistant Carbon Core Guard build
  • Analog-digital display with Neobrite hands and Super Illuminator LED
  • World time, 1/100-second stopwatch, five alarms and auto-calendar to 2099
  • About three years on two SR726W batteries
Cons
  • Mineral glass scratches more easily than sapphire
  • Resin bezel insert and band still show wear over time
  • No solar charging or Bluetooth like some pricier G-Shocks
  • Analog hands can be hard to read in low light without the LED
  • Case is still large at 49.3 × 44.4 mm for smaller wrists

About the Casio G-Shock GM-2100

The Casio G-Shock GM-2100 is an analog-digital quartz watch from the G-Shock series. It has a round stainless steel case with a fixed resin bezel, a silver-tone dial, black hands and index hour markers. The hands and markers use Neobrite luminescence, and a Super Illuminator LED light is built in.

The case has a solid case back and a scratch resistant mineral glass crystal. The shock resistant construction uses a Carbon Core Guard structure, and the bezel is gold ion plated. The watch is water resistant to 200 meters (660 feet).

Functions include date, hour, minute, second, month, a 1/100-second stopwatch, world time, 5 daily alarms and 12/24-hour format. The full auto-calendar runs to the year 2099. Button operation tones can be turned on or off. Accuracy is ±15 seconds per month, and the two SR726W batteries last approximately 3 years.

Questions and answers

Is the GM-2100 worth it over a standard resin G-Shock?
If you want the metal-bezel look and a slimmer case, yes. A plain resin G-Shock offers the same toughness for less, but looks more casual.
How does it compare with the full metal G-Shock models?
The GM-2100 has a steel bezel but a resin case and band, so it is lighter and less expensive than full metal versions. It also lacks solar charging and Bluetooth.
Is it too big for small wrists?
At 49.3 × 44.4 mm and 11.8 mm thick, it is a large watch. Many owners with average wrists find it fine, but slim wrists may find it oversized.
Does it have a light?
Yes. It has a Super Illuminator high-brightness LED light, and the hands and markers use Neobrite luminescence.
What is in the box?
The watch comes in its original Casio box. No extra straps or tools are included.
How long does the battery last?
About three years on two SR726W batteries. It is not solar-powered, so the battery will need replacing.

At Jomashop, for $179.00, 19% under what the other stores charge, as of our latest check.
