Description

This limited edition timepiece is within a collection to commemorate the 145th Anniversary of the beginnings of Seiko as a Tokyo clock and watch repair shop in 1881.

This watch shape is nicknamed by Seiko fans as a ‘Samurai’ – because of its angular shaped design which looks as if it were sliced by a Japanese Samurai sword.

This 200m Diver features a silver dial with LumiBrite on the hands and indices ensuring clarity in the darkest depths. It features an aluminium insert unidirectional rotating bezel designed for safe diving use. The second hand and bezel are in a shade of ‘Seiko Blue.’ On the case back is a limited edition engraving.

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.

*In an actual product, the case back direction might be different from the photograph.
