Grand Seiko Evolution 9 Spring Drive 5 days SLGA015

This Grand Seiko Diver’s watch is powered by Spring Drive Caliber 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 color 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 color and richly textured surface of the dial of this new 200m diver’s watch.

About Grand Seiko

Grand Seiko emerged in 1960 as a high-end watch line from Seiko, aiming to challenge Swiss dominance in luxury watchmaking. The brand quickly established itself with Japan's first chronometer-grade watch and later gained renown for its innovative Spring Drive technology, which combines the best of automatic and quartz movements. In 2017, Grand Seiko became an independent entity, solidifying its position in the luxury watch market.

The brand's design philosophy, known as the "Grammar of Design," was established in 1967 with the Grand Seiko 44GS. This aesthetic approach emphasizes legibility, refined appearances, and distinctive features like multi-faceted markers and hands, a half-recessed crown, and the meticulous Zaratsu polishing technique. Grand Seiko continues to push boundaries in watchmaking, as evidenced by recent innovations like the "Kodo Constant-Force Tourbillon," while maintaining its commitment to precision engineering and unique design language.
