Custom G-SHOCK GA-2100 Mens Watch - Stainless Steel Silver

This is a custom made watch featuring a genuine Casio G-Shock module combined with an aftermarket stainless steel case and strap. Includes original G-Shock tag, box, tin and paperwork.

The GA-2100 Octagon series is the slimmest G-SHOCK ever.

The series has a signature octagonal case, another G-SHOCK first. 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.
