Seiko Prospex "Sea" Solar GMT Men's Watch SKF001J1

Seiko Prospex has unveiled its first ever solar-powered watch with a GMT hand, driven by its own in-house built 5K62 caliber. It has been affectionately dubbed the 'Sumo' by Seiko aficionados due to its shape and size, as well as the 12 o'clock marker, creating a very sturdy aesthetic. The LumiBrite Colour on the 24-hour hand is highly visible even when underwater, while the aqua-coloured dial adds a vibrant touch to the finely-pressed pattern design.
