Japan got the blacked-out one first.
Casio’s GBM-2100LXB-1A2JF went on sale there on November 7. It’s the newest Luxe Black entry in the G-STEEL 2100 line, and it takes the metal CasiOak formula about as dark as it goes. Black ion plating covers the stainless bezel. Gunmetal covers the markers. One blue ring around the glass is the only color on the watch.

Luxe Black is a running series, not a one-off. Earlier entries chased the same monochrome idea in resin and metal. This round adds the GBM feature set on top: Tough Solar charging and Bluetooth phone link, in the slimmest metal 2100 case Casio sells.
Black on black, one blue ring
Blue goes on as a vapor deposit at the outer edge of the glass, so it shows up as a ring rather than a panel.
Hour markers wear a gunmetal vapor finish. Logo and subdial ring accents run metallic silver. Those accents and the hands are the only bright metal on the dial.
A checker pattern textures the dial, matched by a square-dot texture molded into the bio-based resin strap. Casio’s own description leans on the pairing: dial grid and strap dots built to read as one surface treatment from across a room.
Under the styling, the construction is standard G-STEEL. A stainless bezel sits over an inner case of glass fiber-reinforced resin, which is how the line keeps its shock structure at this thickness.
Pushers and crown stay recessed in the case walls. Same as every 2100 since the shape debuted.
Casio pitches this one as the refined entry: matte black tones, metallic accents, details finished to be noticed up close instead of across the street.
Dress-watch manners on a G-Shock. The 2100 line keeps making that combination look normal.
Solar, Bluetooth, 72 grams
Tough Solar runs the watch about seven months on a full charge, stretching to 18 months in power-saving darkness.
Bluetooth pairs with the Casio Watches app for automatic time correction and phone finding. Water resistance is 200 meters. Five daily alarms, a 1/100-second stopwatch, and a countdown timer ride along.
Solar charging, Bluetooth, 200 meters of water resistance. All of it at 72 grams.
Dimensions run 49.3 by 44.4 by 11.9 mm. Weight is 72 g.
Eleven-nine thick is slim work for a metal-bezel G-Shock, and it wears smaller than the numbers suggest because the case walls taper hard.
Phone link covers the daily chores. Automatic time adjustment runs four times a day, world time covers roughly 300 cities, and a phone finder handles the mornings the handset hides in couch cushions.
A dual LED setup lights the dial and the digital window together, so the ana-digi layout stays readable at night.
Price and where it stands
Japanese retail is ¥42,900. Time Station Neo, a Casio retailer in Japan, already lists it at ¥34,320, 20 percent under list inside the launch week.
Casio Europe shows the model as a new November 2026 arrival with no price attached. Casio US hasn’t listed it at all.
US buyers aren’t empty-handed, though. The Watch Connection, a US Casio dealer, takes pre-orders at $310, and that’s the route the boxes on this page use.
Grey-market listings overseas bracket the same watch between roughly $280 and $440. The $310 pre-order sits at the low end of that range.
One trade comes with the finish. Black IP over polished steel shows desk-diving scuffs faster than bare metal does, and the coating wears at the bezel edges first.
Owners of earlier black IP G-Steels know the pattern: the watch ages into a two-tone look, planned or not. Some owners chase exactly that worn-in finish. Others should buy the silver GBM and keep the metal bare.
Against the wider Luxe Black family, this is the one to pick if you want the feature set. Resin versions cost less and skip solar and Bluetooth.
If blacked-out metal is the look and you don’t want a charge cable, get this one. Solar power, phone link, blackout finish, all in the same watch.
