Casio G-Shock Full Metal 2100 Chrono 51.5mm Mens Watch Black
This full metal chronograph combines G-Shock's legendary durability with contemporary functionality. The 51.5mm stainless steel case features an octagonal bezel with circular hairline and mirror polish detailing, echoing the original 1983 design whilst maintaining modern aesthetics. The black dial houses a chronograph complication with subsidiary dials, complemented by a high-brightness LED backlight for low-light visibility.
Powered by Tough Solar technology for sustained operation, the watch connects via Bluetooth to a dedicated smartphone app for atomic timekeeping synchronisation. The full stainless steel bracelet incorporates a dimpled design reflective of classic G-Shock styling. Water resistant to 200 metres, the watch measures 51.3mm by 46.3mm by 12.4mm. This represents the inaugural chronograph addition to the 2100 collection, marrying G-Shock's protective engineering with refined metalwork.
