Meet the "CasiOak": G-SHOCK's Breakout Design Icon
The G-SHOCK 2100 Series watches launched by Casio in 2019 and quickly gained recognition for its sleek octagonal case, earning it the nickname "CasiOak" among collectors. The design resemblance to the iconic Royal Oak is unmistakable, yet the 2100 Series remains unmistakably G-SHOCK in toughness and utility. Lightweight, affordable, and stylish, it bridges G-SHOCK's technical legacy with urban appeal.
