About Grand Seiko SLGC007
Grand Seiko The Tentagraph Evolution 9 Collection
A mechanical chronograph imbued with the majestic presence of Mount Iwate in winter
This mechanical chronograph was created in the Evolution 9 Style, a unique design method that combines the spirit of Grand Seiko and the aesthetic beauty of Japan to reach new heights. The dial captures Mount Iwate, topped with fresh snow, a merger of the harsh winter’s crisp blue sky and the subtle blue tint of the newly fallen snow. The deep snowfall is represented by the snow-blue dial color and an embossed pattern inspired by the mountain’s ridgelines.
This model features the Mechanical Hi-Beat Chronograph Caliber 9SC5 oscillating at a rate of 10 beats per second, which operates continuously for approximately 72 hours (about 3 days) when fully wound.
Grand Seiko SLGC007 Features
A two-layer dial expressing the contrast between rocky ridges and freshly fallen snow
Nature’s beauty and the ever-changing seasons provide boundless inspiration for Grand Seiko. Mount Iwate, visible from the Grand Seiko Studio Shizukuishi, where the brand’s mechanical watches are crafted, presents breathtaking expressions throughout the year. The dial is inspired by Mount Iwate in the depth of winter, with the new snow depicted in snow-blue, while the mountain’s surface peeks through in the form of black sub-dials.
High legibility, a hallmark of the Evolution 9 Style
One signature of the Evolution 9 Style is its dial with redesigned indexes and hands. Created to achieve maximum legibility, their size and shape allow the wearer to read the time with just a glance. Everything about the Tentagraph’s chronograph and time-of-day displays has been thoroughly considered, from the placement of the hands relative to the indexes to the distance between the dial and the hands. By placing the date between four and five o’clock, an index can remain at each of the traditional hour positions while allowing for maximum readability for the time of day and the chronograph sub-dials.

Grand Seiko SLGC007 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
