Grand Seiko, the latest Spring Drive movement and Ever-Brilliant Steel. A perfect combination.
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 9RA2 Spring Drive 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 type of stainless steel that delivers a new level of durability and, as the name implies, has a brilliant white hue that enhances the beauty of this classic Grand Seiko design.
44GS 55th Anniversary Limited Edition
The watch pays homage to the famous 44GS from 1967 whose design was the first ever expression of the Grand Seiko Style. This set of design principles defined Grand Seiko once and for all and still inspires every new creation to this day.
The watch is powered by the revolutionary Caliber 9RA2 which offers a power reserve of 120 hours and a precision rate of +/- ten seconds per month. The movement is assembled and finished by hand and its finely polished bridge, blue tempered screws and power reserve indicator are all visible through the sapphire case back.
It will be available as a limited edition of 550 at the Grand Seiko Boutiques and Salons worldwide.

A dial inspired by the stars
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.
Caliber 9RA2. At the cutting edge of horology.
Caliber 9RA2 delivers significant advances in performance, thanks to innovations that only a fully integrated “manufacture” could create. It offers a power reserve of 120 hours with a precision rate of +/- 10 seconds per month. Remarkably, the movement is thinner than its existing counterpart and makes possible a slimmer and sharper case that is true to the Grand Seiko Style established in 1967 with the celebrated 44GS.
Ever-Brilliant Steel: the world’s most corrosion resistant steel.
Known as Ever-Brilliant Steel, thanks to its brilliant white hue, this steel is more corrosion resistant than that which is used in even the most prestigious watches today.*
* This stainless steel has a PREN (Pitting Resistance Equivalent Number) value 1.7 times higher than that of the grade of steel used in most high-end watches. PREN is a widely accepted standard used to measure corrosion resistance.
The three movements at the heart of Grand Seiko
One of the world's foremost mechanical movements, the culmination of high-precision micro-engineering and the attention to detail of Grand Seiko's expert watchmakers.
Spring Drive is a unique movement that delivers one-second-a-day precision, using just the power of a mainspring.
