G-Shock GMB2100GD-9A

The G-Shock GMB2100GD-9A is where four decades of Japanese toughness meet unapologetic luxury. Part of the Full Metal GM-B2100 series, this men's solar-powered analogue-digital watch takes the octagonal 2100 silhouette — itself an evolution of the original 1983 DW-5000C that started the G-Shock legend — and renders it entirely in stainless steel, finished in gleaming yellow gold ion plating across the case, bezel and integrated bracelet.

The metalwork here is genuinely exceptional. The bezel is formed three-dimensionally through a time-consuming process of forging, cutting and polishing, finished with a circular hairline treatment on its top surface and mirror polish on the slopes — while the bracelet reproduces the dimpled texture of the 1983 original in solid steel, with differentiated hairline and mirror finishes across each link. The dual-layer dial showcases Japanese microfabrication at its finest: precision die moulding by Yamagata Casio, laser-welded components, and vapour-deposited dimensional indices that catch the light like a watch several times the price. Fine resin buffering components hidden between the bezel and case preserve full G-Shock shock resistance, backed by 200-metre water resistance and a screw-lock case back.

Beneath the gold sits a seriously capable engine. Tough Solar power means the battery charges from any light source and never needs replacing, while Bluetooth connectivity to the Casio Watches app keeps the time automatically precise and unlocks around 300 world time cities, reminders and a phone finder. A 1/100-second stopwatch, countdown timer, five daily alarms, full auto-calendar to 2099 and double Super Illuminator LED lights round out the specification, with a clever hand-shift feature that moves the hands aside for an unobstructed view of the digital display. At 44.4mm across and a substantial 165 grams on a one-touch triple-fold clasp, it announces itself the moment it catches the light.

What we love: Gold G-Shocks divide rooms — and that's exactly the point. This is the watch for the man confident enough to wear his toughness gleaming: forged and hand-finished Japanese steel, an icon's silhouette, and engineering that never asks for a battery change. It reads as pure luxury on the wrist while remaining, underneath it all, indestructibly G-Shock. Covered by a 2-year warranty. Product code: GMB2100GD-9A.
