Casio G-Shock Bluetooth Solar 2100 Series Yellow Smartwatch GA-B2100C-9AER

Built for everyday wear with a bold pop of colour, the Casio GA-B2100C-9AER smartwatch from the G-Shock 2100 Series pairs a round plastic case with a yellow plastic strap and traditional buckle fastening. A yellow dial sits beneath mineral crystal glass, while a quartz movement and solar power keep time with an accuracy of +/- 15 seconds per month.

Bluetooth connectivity links to compatible smartphones, supported by practical functions including world time, stopwatch and countdown timer. The display includes date and weekday, with an automatic calendar that maintains the correct date once set. For low-light conditions, the dial offers Auto Light illumination with selectable duration, plus Neobrite coating on the hands. Shock-resistant construction and 100-metre water resistance complete the specification.
