SUMO

Seiko Prospex Scuba Diver SBDC003 6R15 – Sumo

Seiko Prospex Scuba Diver 200m SBDC003 known as Sumo.

This is Japan Domastic Market model not available outside Japan, however there few Japanese websites which sell them internationally.

They have better movement then usual Seiko automatic watchae – 6R15, which has hack (seconds hand stop at second crown position – so it is possible to set precise time). Accuracy is +6 sec /day on hands and -2.5 sec/day laying on the desk with face 30 degree up.

This watch hooks me up to diving watches.
