SEIKO PROSPEX – Sumo Black Series Limited Edition SPB125J1

Since Seiko launched Japan’s first diver’s watch in 1965, the brand’s innovative technology has changed global dive watch standards. This imposing Seiko Prospex Black Series Sumo Diver Watch is a Limited Edition of only 7,000 pieces worldwide. Affectionately christened the “Sumo” by Seiko fans because of it’s size, dimensions and the shape of the 12 o’clock marker, this is a practical watch with rugged good looks.

Water resistant to 200 m/660 ft the Seiko Prospex Black Series Sumo Limited Edition has all the attributes you would expect from a professional Diver’s watch. Firstly, the heavy-duty 45mm case is in black PVD coated stainless steel and ergonomic in shape. The black dial has high-visibility hour markers and hands coated in Lumibrite. A legible minute track is also at the extreme edge of the dial.  Surrounding the dial, there is a uni-directional turning bezel in black.

Equipped with an automatic 6R35 calibre movement, the Seiko Prospex Black Series Watch is an absolute must for anyone looking for a comfortable and well-made Diver watch.
