Grand Seiko SBGW231G Features : 

The natural beauty of time

Kanro is the “Sekki” or season in Japan that is the harbinger of winter. It falls in early October, when the rice is ready to be harvested before the cold sets in. The morning mist covers the plants in dew and a pale mist hangs lightly over the fields. All is mellow and calm. The dial of this Grand Seiko hand-winding timepiece is as pure and rich as the Autumn light. It is at one with nature.

Watches inspired by nature

 

A classic look, with the Grand Seiko touch

Grand Seiko SBGW231 Classic

The case is round. The dial is simple. The case is a conventional 37.3mm in diameter. In all its fundamentals, this is a classic “dress” watch. But look more closely and the unique character of Grand Seiko is revealed. The lugs are curved. The case is Zaratsu polished to a distortion-free finish. The hands and indexes are diamond cut to reflect the light from every angle. The more you look, the more you understand why the original design team of Grand Seiko in the 1960’s talked of ‘the sparkle of quality’.

 

As comfortable as a watch can be

Grand Seiko SBGW231 Comfort

How can a watch be made to sit so comfortably on the wrist? It all starts on the inside. This Elegance timepiece is powered by the hand-winding Caliber 9S64 which is so slim that the entire case is just 11.6 mm in depth. The dial, hands and sapphire crystal are curved and the lugs are shaped so as to allow the leather strap to wrap snugly around the wrist. When you wear a Grand Seiko, it just feels right.

Grand Seiko SBGW231G 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
