Dressed in black, the Casio CasiOak GM-S2100B-8A is a timepiece from the G-Shock 2100 Metal Covered Series, released as part of the CasiOak collection. This GM-S2100 CasiOak watch features a stainless-steel, octagonal design with a 41mm case and a dark bezel with a rounded hairline finish. A mineral glass crystal protects the inner components, including the black dial. It has an analog-digital display with features such as a countdown timer, a world time function, a stopwatch, five daily alarms, an LCD time display in 12/24-hour format, an hourly time signal, an auto-calendar, a double LED backlight, and light-gray hour and minute hands. Other features include shock resistance and a water-resistance rating of up to 200 meters. A black resin band with buckle-style closure finishes off the design. Our experts particularly love this watch’s slim, octagonal design with a bold finish, which gives it a luxurious feel.
