Seiko Prospex SFK001 Sea Sumo Solar GMT Blue

Combining the ease and accuracy of solar quartz with a 24-hour hand for tracking a second time zone, it's everything you expect from a Seiko diver's watch, and so much more.

The robust 45mm stainless steel case and 200 meters of water resistance allow this diver's watch to go anywhere a serious explorer can imagine.

Under the stylish pressed-pattern dial, the new 5K65 movement turns ambient light into accurate timekeeping.

The first Seiko solar-powered watch with a GMT function, its brightly colored 24-hand opens a new frontier for the Seiko diver's watch.
