Product Specifications

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.

Customer picture of Seiko Prospex King Sumo Grey ‘Gradation’ Diver SPB323J1 I don't like ordering online especially around the holidays. But I had saved all year and I saw a lovely king sumo in first class watches. The checkout was easy and fast. Then the communication started which is brilliant as after paying several hundred pound you don't wanna feel forgotten. 24 hours later postie rang my bell. Great service. Lovely watch. Thank you.
