Its slim profile, a departure from typical G-Shock designs, features an octagonal bezel and a black resin case and strap. The analog-digital display provides versatile timekeeping with features like world time, stopwatch, and countdown timer, all protected by G-Shock's signature shock resistance and 200-meter water resistance.
History
Launched in 2019, the GA-2100 series, nicknamed the 'CasiOak' due to its resemblance to luxury Audemars Piguet Royal Oak models, revitalized the G-Shock brand. It appealed to a new demographic seeking a more streamlined yet robust timepiece. Casio, founded in 1946, has a long history of innovation in electronic products, with G-Shock debuting in 1983 as a revolutionary shock-resistant watch.

The watch's carbon fiber reinforced resin case further enhances its toughness.
