Up for sale is a Casio G-Shock GD100-1B — the XL-sized digital tank of the G-Shock lineup. At 55 mm wide and 17.4 mm thick, this is one of the largest digital G-Shocks in the standard catalog, built around an oversized split-screen LCD that displays main time, world time, and chronograph data simultaneously. Packing a 7-year battery (CR2025), full world time across 48 cities, 5 daily alarms with flash alert, 1/100-second stopwatch, and a 24-hour countdown timer, it's a feature-loaded workhorse in an unmistakably bold package. The all-black matte finish with the high-brightness LED backlight keeps it tactical and legible day or night.
The GD-100 series launched around 2010 as G-Shock's answer to the largest digital display in a standard model. The split-screen layout with multiple simultaneous readouts sets it apart from the simpler 5600/6900 series, and the blacked-out 1B variant is a perennial favorite for its low-profile look despite the massive dimensions.
