Founded in Tokyo in 1946, Casio changed the landscape of consumer electronics before launching the G-Shock in 1983 — a watch built around a single principle: absolute indestructibility. The MR-G sits at the very top of that forty-year story, hand-assembled at Casio's Premium Production Line in Japan from materials that bear little resemblance to the resin and steel of a standard G-Shock. The MRG-B5000D-1 is the natural titanium expression of the MRG-B5000 series — a direct homage to the original DW-5000C from 1983, rebuilt from the ground up in aerospace-grade metals and finished to a standard that places it firmly among the most technically accomplished sport watches made anywhere in the world.

Reference MRG-B5000D-1 is a 49.4 x 43.2 mm Tough Solar digital watch, 12.9 mm in thickness, weighing just 114 grams despite its full metal construction. The Ti64 titanium case and DAT55G titanium bracelet — a special alloy three times harder than pure titanium — carry a titanium carbide coating that delivers a warm silver metallic sheen alongside exceptional scratch resistance. The 25-component bezel top is crafted in COBARION, a cobalt-chrome alloy four times harder than pure titanium, individually polished using Casio's Sallaz mirror-finishing technique. The black negative LCD dial retains the iconic brick pattern and red line of the original 1983 design. The Tough Solar movement powers Multi-Band 6 radio-controlled time synchronisation across six global atomic clock transmitters, Bluetooth smartphone link via the Casio Watches app, world time across 39 cities, 1/100-second stopwatch, countdown timer and five daily alarms — with a power reserve of approximately 22 months in power-saving mode. The sapphire crystal sits above. Water resistance is rated to 200 metres. The DAT55G titanium bracelet is fitted with a one-press three-fold tight-lock deployant clasp.

This Casio G-Shock MR-G is in near mint condition and comes as a full set.
