The case measures 33.7 mm across and 6.6 mm high, which is considered the large version of the Tank. Inside is a hand-wound manufacture caliber 1917 MC. Available as a limited production series. $13,100

This month, G-Shock announced a new watch in collaboration with the Royal Navy. Inspired by the UK Navy’s famous Queen Elizabeth Aircraft carrier, the Royal Navy Frogman (Ref.

The metal strap keeper is engraved with the Royal Navy logo, and the caseback has G-Shock’s iconic frog holding an anchor. The GWFA1000 is water-resistant to 200 meters and features Bluetooth connectivity that allows you to review diving logs on a smartphone through the Connected App (both iOS and Android). With the dive log, the user can mark dive locations, time, date, number of dives, plus include photos. With Tide Point, the user can select from a preset list of some of the world’s most famous dive points or set their own. $1,000
