March 19, 2020


Tokyo, March 19, 2020 — Casio Computer Co., Ltd. announced today the release of the GMD-B800SC, a new compact digital model in the G-SQUAD lineup of watches for sports and fitness, which belong to the G-SHOCK brand of shock-resistant watches.

The new GMD-B800SC is a smaller version of the GBD-800, which is popular for its useful features for daily fitness and workouts and its variety of vividly colored designs. The downsized case width of the new watch offers an improved wrist-fit and makes it easy to wear not only for women with a taste for the G-SHOCK “menswear” style, but also for those who favor compactness.

The new GMD-B800SC, available in two models, comes in color schemes inspired by sportswear and shoes. The black model, with a touch of vivid neon pink for the indicator on the dial and the case back protector, while the model with a black case and a vivid neon yellow band delivers a style that goes well with sportswear.

Functions include a triple-axis accelerometer that automatically tracks step count as well as running or walking pace simply by wearing the watch on the wrist. The daily step count is displayed on the watch, and the user can check the indicator to see whether the day’s step count goal was achieved. By pairing the watch to a smartphone via Bluetooth®, the user can display the daily step count and calories consumed using the G-SHOCK Connected app. This app also enables users to create workouts with five timers for interval training to promote their daily fitness.
