Casio G-Shock GA-2100LXB: New images of metallic accent watches leak

Two new Casio G-Shock GA-2100 series watches have been unveiled. The GA-2100LXB-1A and the GA-2100LXB-1A9 were rumored alongside the GM-2100LXB-1A and the GM-2100LXB-1A9 watches earlier in May 2026. These four watches are thought to be known as the Luxury Black collection.

Now, images of the Casio G-Shock GA-2100LXB watches have been leaked at the Vietnamese retailer G-Shock Hai Phong. Both versions have black resin casing, measuring 48.5 x 45.4 x 11.8 mm (~1.91 x 1.79 x 0.46 inches), with a matching strap. However, the two variants have different accent colors. For example, the GA-2100LXB-1A had dark metallic gray indexes and a similarly colored indicator dial ring, with brown digits on the black background digital display. By contrast, the GA-2100LXB-1A9 has golden-hued indexes and indicator elements, with gold tone numbers on the inset display.

Casio’s G-Shock GA-2100 analog-digital watch has an octagonal bezel, making it a CasiOak model. It typically features the brand’s Carbon Core Guard structure, with 200 m water resistance and a three year battery life. There are tools like a 1/100th second stopwatch, a countdown timer and multiple daily alarms. Plus, users can choose from a list of 31 time zones across 48 cities.

It is unclear when Casio will officially announce the G-Shock GA-2100LXB-1A and GA-2100LXB-1A9 watches. At the Vietnamese retailer, they are marked as June 2026 releases, though there is no indication as to how much they could cost in this or other markets.
