The Grand Seiko Evolution 9 Collection Spring Drive 5 Days Diver’s 200m

This Grand Seiko Diver’s watch is powered by Spring Drive Calibre 9RA5 which offers an accuracy rate of ±10 seconds per month and a five day power reserve. It is made from High-intensity Titanium, a material that is 30% lighter than stainless steel and even more impervious to scratches and corrosion. To further enhance its durability, the rotating bezel is in ceramic to protect the watch from being scratched.

The dial is deep black in colour and has a strongly patterned surface, inspired by a particular aspect of the oceans that surround the Japanese archipelago and that are criss-crossed by water currents of great power. One such is the Kuroshio Current, also known as the Black Stream. It flows northwards past Japan towards the Arctic North Pacific and is one of the largest ocean streams in the world. The dynamic and sometimes violent tides caused by the Black Stream inspire the deep black colour and richly textured surface of the dial of this new 200m diver’s watch.
