A dive watch for far-flung adventure

A proper diving adventure doesn't start until you're a few time zones from home, which is why this Seiko Prospex Solar GMT Diver makes for the perfect dive buddy when you're far from home. Continuing the traditions of Seiko's mastery of precision timekeeping instruments built for use in extreme environments, this 200m water resistant 'Solar Sumo' reference (nicknamed so, for its generously cushioned 'barrel-shaped' case) is built using Seiko's 5K65 solar-charged "Flyer GMT" quartz movement for full timekeeping autonomy and staggering accuracy, while faithfully keeping track of home time, no matter where you are in the world.
