Seiko Prospex King Sumo Blue Gradation Diver's Automatic Watch

Ref: SPB321J1

Highlights:

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.
As part of the Prospex collection, this model is a guaranteed premium timepiece with all the finery expected from Seiko's superior sport model series.
This latest design has been updated 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 modernised.
Premium sapphire crystal glass provides better protection from scratches in your daily life.
The dial features a fine pressed pattern dial with gradations of blue.
Powered by a 6R35 automatic movement (with manual winding capacity) which beats at 21,600 times an hour. This calibre movement is complete with 24 Jewels and a 70 hour power reserve.
The crown has screw-down protection to prevent it from being pulled out by any accidental operation. Greater security is achieved by positioning the screw-lock crown at the 4 o'clock position.
The uni-directional rotating bezel: The precise and safe operation of the uni-directional bezel prevents accidental rotation. This is to prevent the watch from displaying the elapsed time shorter than it actually is.
The easy to read dial features luminous indexes and hands.
