Heritage 44GS 55th Anniversary Hi-Beat Limited Edition

Grand Seiko's state-of-the-art Hi-Beat movement, now with Ever-Brilliant Steel

For over sixty years, advances in the fundamentals of watchmaking, precision, durability and beauty, have been of paramount importance to Grand Seiko. With the Caliber 9SA5 high-beat movement launched in 2020, Grand Seiko took an important step forward in precision and overall performance. This watch features this movement in a case that is made of Ever-Brilliant Steel, a stainless-steel alloy that features even greater corrosion resistance than what is typically used across the watch industry today. Visually, it also has a brilliant white hue that enhances the beauty and finishing of the watch.

The watch pays homage to the famous 44GS from 1967 whose design was the first ever expression of the uniquely Japanese Grand Seiko Style which, ever since, has been its visual signature. It features the high-beat watch powered by the revolutionary Caliber 9SA5, which offers a power reserve of 80 hours thanks to its enhanced energy efficiency. It is offered as the case and bracelet material is Ever-Brilliant Steel and the movement is specially designed with tempered screws to mark the 55th anniversary of 44GS. 

The dial has a depth and a texture that attract the eye and take the imagination upwards towards the sky at night. The deeply etched pattern is that of the elliptical orbit of the stars as they move across the heavens and it captures the serene passage of celestial time with its flowing, unbroken lines.

The case measures 40mm across and 11.7mm in thickness, making it thinner than 44GS models offered in past Mechanical options. This is due to the reduced thickness of the 9SA5 caliber itself, which has a power reserve of 80 hours, an accuracy rate of +5 to -3 seconds per day, and a rate of 36,000 bph. The case comes with a box-shape sapphire, an exhibition caseback, and bracelet.

Limited to 550 pieces.
