About Grand Seiko SBGH299

Grand Seiko “Mount Iwate” Automatic Hi-Beat 36000 Heritage Collection

The 44GS design presented in Ever-Brilliant Steel with a Hi-Beat 36000 Movement

The 44GS of 1967 established, once and for all, the “Grand Seiko Style,” a design language centered on the idea of a wristwatch with “sparkle and quality.” The new Ref. SBGH299 presents this classic design in the cutting-edge, anti-corrosive material Ever Brilliant Steel, an alloy with a pitting resistance 1.7 times that of the normal steel typically seen in luxury watches.

The unique design, whose primary feature is a polished, undistorted surface, reverberates with a beautiful radial dial pattern, giving rise to an expressiveness that weaves together light and shadow in an aesthetic sense that the Japanese have appreciated since ancient times.

The movement is the Hi-Beat Caliber 9S85, which beats 10 times per second and grants more stable precision through resistance to interference and maintaining consistent accuracy.

Grand Seiko SBGH299 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
