Exciting news has come out of Japan with a major update to the very popular GA2100 Carbon Core G-Shock. The new GA-B2100 models feature two of G-Shock's key 21st-century developments – Bluetooth connectivity to the G-SHOCK Connected smartphone app and Tough Solar charging, which will allow a watch to run indefinitely in the presence of light, without the need for a new battery. 

The GA-B2100 is a slimmer G-Shock watch measuring 48.5 x 45.4 x 11.9 millimetres and weighing about 52 grams. It is 0.1 mm thicker and 1 gram heavier than the GA-2100, making it the slimmest solar-powered G-Shock watch available.

On a full charge, the watch can operate for about seven months with normal use without further exposure to light, or up to eighteen months when stored in darkness with power-saving enabled. Regularly exposing the watch to bright light will provide maintenance-free operation for many years.

Available from Christies in June 2022. Price to be announced
