Original Post:

Japanese fan blog Great G-Shock World reported that a metal-covered G-Shock GM-2100 series is planned for a future release. Like other GM models (GM-5600, GM-6900, GM-110), the GM-2100 is based on its all-resin counterpart and has a stainless steel bezel. Considering the popularity of the GA-2100 series, a metal-covered “CasiOak” was inevitable, but we were not expecting to see it so soon. This release has not been officially confirmed yet, and the release date is unknown. (Update: Esquire HK reported that it is coming in 2021, and we expect it to arrive by the holiday shopping season.)

The watches look exactly like what you’d expect from a metalized 2100 bezel. Each model has a resin band with a unique grid-like texture. There haven’t been any other GM models with a metal or composite band, so we are not expecting that with the GM-2100 series, but we wouldn’t be surprised to see some sort of update for the 2100 series in the future. As with other GM models and their counterparts, the functions are expected to be the same as the GA-2100. The debut models include the silver GM-2100-1A, dark gray and green GM-2100B-3A, dark gray and red GM-2100B-4A, and blue GM-2100N-2A.

Update: GGW later reported that the GM-2100 series will be released in August and that the price range will be from 26,400 to 28,600 yen.

Update 2: G-Shock U.S. is expected to release all four models. The GM2100-1A will have a list price of $200, and the GM2100B-3A, GM2100B-4A, and GM2100N-2A will have a list price of $220 each.

If the strong sales of the GA-2100 series are any indication, the GM-2100 series will also be very popular and some of the models may sell out quickly.

Update: A smaller G-Shock GM-S2100 series is also reportedly coming, which includes the silver GM-S2100-3A with green dial and band, black IP GM-S2100B-8A with black dial and band, and rose gold GM-S2100PG-1A4 with rose gold dial and black band. These models have smooth resin bands. The GM-S2100-3A and GM-S2100B-8A have a unisex style.

US product pages are now up with note “Pre-order begins 8/23”!

https://www.gshock.com/watches/search?s=gm2100

I’ve never pre-ordered directly from gshock.com before. When it says 8/23, does it mean the pre-order will be available at mid-night Eastern Time that day?

I found a previous pre-order announcement page for the 18K Pure Gold Square and it seems to suggest pre-ordered start at midnight ET.

GM-2100 has no carbon core guard, it goes back to resin case material. Just got mine today in Singapore, and the back has changed to the classic shock resist instead of carbon core guard.
