Casio GM-2110D-2AER

The Casio GM-2110D-2AER brings metal-covered refinement to the classic 2100 series platform. That stainless steel bezel transforms the aesthetic from pure resin sports watch to something approaching premium finish. The navy blue dial provides distinctive colour that stands apart from standard black whilst the octagonal bezel maintains the CasiOak DNA that made the 2100 series instantly recognisable. This isn't full metal construction, but the metal bezel adds both visual refinement and physical protection where it matters most.

The metal bezel resists scratches and impacts that would mark pure resin, whilst creating premium tactile experience when adjusting functions. The navy dial brings personality without the extreme boldness of yellow or orange variants—sophisticated colour choice that works across casual and smarter contexts. The slim 11.9mm profile ensures this doesn't stand proud like typical oversized G-Shocks, whilst the 48.5mm case maintains wearable dimensions.

Shock resistance handles the impacts that destroy conventional watches—the Carbon Core Guard structure protects the module with carbon fibre-reinforced resin. Water resistance to 200 metres covers swimming, snorkelling, and water sports confidently. The mineral glass resists scratches from daily abuse. Weight increases slightly compared to all-resin models but remains reasonable.

Functions include world time, stopwatch with 1/100-second accuracy, countdown timer, five daily alarms. The Super Illuminator LED provides bright illumination for both analogue hands and digital display. The perpetual calendar runs until 2099 without adjustment. Battery life approaches 3 years on standard cell.

The resin band handles sweat, saltwater, and rapid cleaning without degradation. The combination of metal bezel with resin case and band creates interesting visual contrast—premium where visible, practical where functional. This approach prioritises both aesthetics and utility intelligently.

This GM-2110D-2AER serves anyone who wants G-Shock toughness with elevated aesthetic. The metal bezel justifies the premium over all-resin models, whilst the navy colourway adds distinctive personality that black cannot match. Casio proved that tough watches can also be refined—this metal-bezel 2100 demonstrates that philosophy without compromise.
