Today G-Shock announced its first full metal GMB2100 series, which is the metallic version of the popular octagonal bezel watches, dubbed by enthusiasts as the “CasiOak” — and that will now be available on a metal bracelet.

The new G-Shock GMB-2100 Series will be available for sale starting August 12, 2022. At launch, there are three variations. The hero model shown at the top is the GMB2100D-1A (silver) which will retail for $550, and the GMB2100BD-1A (dark gray IP) and GMB2100GD-5A (copper IP) will retail for $600.

According to Casio, “the premium full-metal design of the GMB2100 series is achieved using a three-step surface-finishing technique, which results in a distinct, 3-dimensional appearance on the case/bezel. The technique includes a circular hair-line finish on the top surfaces, a vertical hair-line finish on the side surfaces, and a luxurious mirror-like appearance on the main part of the bezel. The 3-D look is continued on the dial with indexes and inner-dials, which utilizes a vapor deposition treatment to further achieve the sharp detail across all three models.”

The watches utilize fine-resin between the bezel and inner-case for shock absorption, which is a hallmark of G-Shock, that is, the ability to resist extreme shocks and impacts.

Innovative three-prong strap/bracelet connections and screw-in caseback are also adopted in this newest series. The depth rating of 200 meters, which is typical across G-Shocks, is maintained.

In addition to Bluetooth syncing and solar powering of the ultra-accurate Japanese quartz movement, the GMB2100 Series features a Double LED (Super Illuminator) light, 5 alarms + hourly time signal, a 1/100Stopwatch (24 Hr), a countdown timer (60 Min), a full auto calendar, World Time (38 Timezones, 38 Cities+ UTC) up to 300 with the app, a hand shift feature, date/month display swapping, multi-lingual day of week display (En, Es, Fr, Ge, It, and Ru).

When connecting the G-Shock Connected app, which is how the watch automatically updates the time, multiple times per day, there are also extra features that can be done within the app, including simple watch setting, timestamp with location, calendar reminder, and a unique phone finder function.

Like the existing metallic GM2100 Series, the new GMB2100 Series measures 44.4 mm in diameter, however, the case is 12.8 mm, which is a millimeter thicker than the GM2100 Series, which we previously reviewed here. Naturally, with a full stainless steel bracelet versus a strap, the weight has increased as well, to 165 grams (up from 71.5 grams on a resin strap).
