About Grand Seiko SBGA407G

A Spring Drive model with a classic case and blue “Snowflake” dial

A classic mechanism with a detailed focus, Spring Drive enables high precision equal to that of a quartz watch while using a mainspring used in a mechanical watch as a power source.

DESIGN

Snowflake dial

The Snowflake dial used for the first time in 2005 was colored with pale blue to image the snow from the Shinshu Watch Studio, the birthplace of Spring Drive.
It has succeeded in realizing a designer’s idea of expressing the beauty of Shinshu on the dial, and is characterized by a texture that shows a rough snow surface, which is caused by severe cold.

AUTOMATIC SPRING DRIVE 3-DAY

Caliber 9R65

Our company unveiled Spring Drive in 1999, but its lack of a sufficiently effective automatic winding mechanism and 72-hour power reserve prevent its adoption in the Grand Seiko line. After a further four years of development, the first Grand Seiko 9R Spring Drive was created.
The winding system and drive time were improved from the existing 48-hour manual winding system to an automatic 72-hour power reserve. The automatic winding mechanism uses Seiko’s original Magic Lever mechanism developed in 1959, but with improved productivity, maintainability, and durability to enhance winding efficiency.
Caliber 9R65 is currently the most standard of the 9R Spring Drive movements, and is used in many Grand Seiko models.

Grand Seiko SBGA407G Movement

Grand Seiko SBGA407G 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:

  1. Double width index at 12 o’clock
  2. Multi-faceted rectangular markers
  3. Highly polished bezel
  4. Highly polished planes and two-dimensional surface
  5. Half recessed crown
  6. Flat dial
  7. Multi-faceted hour and minute hands
  8. Curved side line
  9. Reverse slanted bezel wall and case side
  10. Dress style with simple but beautiful design
  11. Zaratsu polishing
