Seiko Prospex has unveiled its first ever solar-powered watch with a GMT hand, driven by its own in-house built 5K62 calibre. 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. The 200m water resistance is coupled with a stainless steel case and energy-efficient power generation.Prospex is a combination of the words 'Professional' and 'Specifications.' These timepieces from Seiko have been designed to be functional, reliable and long-lasting, meeting the requirements of daring and courageous individuals in extreme conditions. Seiko has been transforming dive watch standards since the launch of Japan's first diver's watch in 1965.

Super happy with this watch! I own a couple of Seiko Sumo automatics already, and this solar quartz is just as beautiful and even more accurate. Just set it and forget it. Its a true travelers GMT, and the second hand falls right on the hash marks. I ordered it from Japan on a Monday, and it was at my house by Thursday. Unbelievable!
