Prospex King Sumo Grey ‘Gradation’ Diver Mens

This watch shape is affectionately named ‘Sumo’ by Seiko fans because of its size and shape and the 12 o’clock marker – it’s a substantially strong looking timepiece. This latest design has been upgraded with new modern features, including a ceramic bezel and super hard coating on the case and bracelet for durability. A new 3 row bracelet has been specifically made for this model, while the clasp has also been upgraded. The dial features a fine pressed pattern dial with gradations of grey. Prospex is a combination of the words ‘Professional’ and ‘Specifications.’ Seiko Prospex timepieces are designed to be practical, reliable and durable; to meet the high standards required in extreme environments for sports lovers and adventure seekers alike. Since launching Japan’s first diver’s watch in 1965, Seiko’s innovative watchmaking has changed global dive watch standards.
