Grand Seiko SLGW005

This timepiece is limited to only 1,200 pieces worldwide.

This piece is a recreation of the 45GS – Grand Seiko’s first manual-winding timepiece with a 10-beat calibre. The original 45GS, the 4520-8000, was released in November 1968, only one year after the launch of the 44GS which became the blueprint for subsequent Grand Seiko Style. The 45GS was prized for its high precision, regardless of position or external disturbances and, despite its popularity, was no longer made after 1971.

Within a recognisable steel 45GS case design is a dial designed with the same off-white colour as the original, accompanied by a crocodile leather strap.

This recreation offers the original design but with an updated modern in-house 9SA4 hi-beat movement – the first Grand Seiko manual-winding 10-beat movement created in over 50 years, first launched at 2024 Watches & Wonders Geneva exhibition. With its impressive power reserve of 80-hours, it remains slim at only 10.4mm with a +5/-3 second per day accuracy.

Every Grand Seiko features signature high standards of precision, durability and legibility, handcrafted in Japan by Takumi artisans.
