About 9S Mechanical
In 1968, Grand Seiko introduced Japan’s first automatic 10-beat watch (61GS) to the world.
In 2009, 10-beat Caliber 9S85 surpassed the original, with high precision parts created using sophisticated modern technology assembled with skills honed over the many decades of Grand Seiko’s watchmaking.
Innovations to the precision controlling mainspring, the hairspring, and the escapement mean that the 9S Mechanical is not simply a revival of the 10-beat movement of the past, but an entirely new incarnation of this high-precision movement.
Grand Seiko SLGH009 Main Concept :
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.
With its highly efficient Dual Impulse Escapement, Grand Seiko free-sprung balance and twin barrel construction, Caliber 9SA5 delivers a precision rate of +5 to -3 seconds per day and a power reserve of 80 hours. The caliber represents the very finest in modern watchmaking, combining unique and advanced technologies with craftsmanship of the highest order.
When seen through the sapphire case back, different textures are seen to be in harmony. The side of the movement has a matte finish and a subdued tone that absorbs the light whereas the ridges, edges and screw holes are sharply cut and polished to a brilliant finish that sparkles with precision. The tempered blue screws and gold tone add bold accents of color.
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.

Grand Seiko SLGH009 History :
Prior to 1960, to challenge the status of Swiss watches and change the perception of Japanese watches, Daini Seikosha and Suwa began the discussion of a product line that can match the quality of Swiss watches under the suggestion of the parent company. At the time, Suwa Seikosha Co. was in charge of manufacturing men’s watches, so it was decided that Suwa would be producing the first Grand Seiko (GS).
The first Grand Seiko was released in 1960, it was based on Seiko’s previous high-end watch, CROWN. This Grand Seiko has a 25-jewel, manual-winding, 3180 caliber, and only 36,000 units were produced. This was also the first chronometer-grade watch manufactured in Japan, and it was based on Seiko’s own chronometer standard.
The design language of the Grand Seiko was set in 1967, with the creation of Grand Seiko 44GS. The 44GS set the ground for all future Grand Seiko with nine elements. These elements help improve the legibility of the watch under different situations, and create a sharp, crisp visual impression:
- Double width index at 12 o’clock
- Multi-faceted rectangular markers
- Highly polished bezel
- Highly polished planes and two-dimensional surface
- Half recessed crown
- Flat dial
- Multi-faceted hour and minute hands
- Curved side line
- Reverse slanted bezel wall and case side
- Dress style with simple but beautiful design
- Zaratsu polishing
