About Grand Seiko SLGC006
Grand Seiko The Tentagraph Evolution 9 Collection Limited Edition
A mechanical chronograph that imparts the spirit of Mt. Iwate reflecting the morning sunrise
This mechanical chronograph, which has been created in the Evolution 9 Style, takes the fusion of Grand Seiko’s spirit with the aesthetic sensibilities of Japan to a high level. The dial pattern is reminiscent of Mt. Iwate, the peak visible from Grand Seiko Studio Shizukuishi, where Grand Seiko’s mechanical watches are manufactured. Its copper-pink color exudes a dignified presence as if bathed in morning sunlight.
Powered by the Caliber 9SC5, a chronograph movement vibrating at 10 beats per second, this creation operates continuously for up to about 72 hours (about 3 days) when fully wound.
Limited edition of 300 pieces.
Grand Seiko SLGC006 Features
A striking dial pattern that evokes Mt. Iwate
Mt. Iwate is thought to have been formed around 700,000 years ago and has been one of the most active volcanoes in all of Japan, a country with more than 100 active volcanoes. One can sense the history of this soaring peak from its rough surface, etched by the traces of lava flows that extend along the north side. The striking radial dial pattern is inspired by a bird’s-eye view of Mt. Iwate’s ridge line.
High legibility, a hallmark of the Evolution 9 Style
The space between the hands and the dial and indexes has been reduced as much as possible, allowing the wearer to see the time at a glance, even on a chronograph that displays a wealth of information. The date display, placed between the four and five o’clock positions, allows all twelve indexes to be placed in a way that ensures maximum legibility of the sub-dials.
The Tentagraph Caliber 9SC5
The Tentagraph’s name describes key features of the Caliber 9SC5 movement inside: Ten beats per second, three days of power reserve, automatic winding, and chronograph. Fully wound, the watch runs for 72 hours even with the chronograph in operation.

Grand Seiko SLGC006 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.
Design style
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
