The Casio G-Shock “MR-G” series is an extremely limited, luxury line that blends all of the best shock resistance technology that the G-Shock name has to offer, with the trappings of a luxury watch. This MR-G 8100B-1AJ is the second in the series, which features a titanium bracelet and case — both of which have been given a highly scratch-resistant double-hardening treatment. The case houses signature G-Shock amenities like an alarm, world time, 1/20th second stopwatch and 6 ban radio control. It is constructed around G-Shock’s resistance to seven key elements: electric shock, gravity, low temperature, vibration, water (up to 200 meters), shock and toughness. And like any traditional luxury watch, the MR-G would be replete without a scratch-proof and AR-coated sapphire glass face, gold circuit mounts and hand-engraved details. The watch will be available for the debut of the Casio London concept store later this month, for £2,500 GBP (approximately $4,000 USD).
