Grand Seiko SBGA373

44GS modern design model powered by Spring Drive

Powered by Grand Seiko’s unique Spring Drive caliber, this model features 44GS Contemporary Design, a contemporary take on the design of the 44GS, which was launched in 1967 and formed the cornerstone of the Grand Seiko design philosophy, Grand Seiko Style.

The combination of a tempered steel hand and a dial with a thick, silver radiant finish that makes use of Grand Seiko’s special technology delivers simple and sophisticated quality that wearers can enjoy at any age, coupled with the elegantly radiant case achieved through Zaratsu polishing.

The movement of the blue steel second hand over the dial further highlights Grand Seiko’s original glide motion, reflecting the natural and continuous flow of time itself.

It has a 72-hour (3-day) power reserve, and a power reserve indicator on the bottom left of the dial.
