What makes the Casio GA-2100 the perfect complement to any streetwear ensemble is the colour palette. It comes in various colours but this new edition is a monochrome colour pallette. Underneath the hood, the GA-2100 has more than enough invested in engineering to match its good looks. Its Carbon Core Guard structure has stood the test of time in providing next-level toughness in a lightweight format. An auto-LED light also provides great legibility to the analogue-digital dial and LCD display. The resin band combined with 200-metre depth rating makes the GA-2100 the go-to piece come rain or shine. Features such as time zone settings, stopwatch function, countdown timers and alarms provide versatility and unbeatable utility.
