Seiko Prospex Solar Sumo GMT Men's Watch Silver
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.

I bought both the green & blue versions of this Sumo GMTs from Starbuy. They were nicely packed & delivered quickly. The watch fits my wrist perfectly. I love the traveller GMT movement and uniquely coloured dial & bezel ring looks great. Thanks Starbuy !!

Great work guys.
This Seiko sumo gmt is my candidate for a single watch, watch collection. You have the robustness of a 200m dive watch, with the versatility of a gmt complication, with adjustable local hour hand.Seiko's lume is legendary, and with the solar powered movement, it's a set and forget watch.The only thing that lets it down is the bracelet. With drilled lugs, however, it's easy enough to swap it for another strap, which was always my intention, so I wasn't bothered by this.Price wise, it's not cheap, but you are getting a high quality timepiece and I thoroughly recommend it.
