About Grand Seiko STGK013

Grand Seiko Elegance Collection 

A women’s mechanical creation with all the natural elegance of Grand Seiko

Thanks to the slim profile and powerful performance of the new Caliber 9S27, new design possibilities have been created.

Their design respects the heritage that was born in 1967 with the classic 62GS with its bezel-free construction, sharply angled hands and markers and highly polished surfaces. The new design combines the strong, distinctive look of one of Grand Seiko’s seminal creations with a fresh, soft and feminine grace.

Grand Seiko STGK013 Concept :

Grand Seiko STGK013

The Grand Seiko STGK013 is made of stainless steel. The case is 30.6mm in diameter and 12.7mm in thickness. The Grand Seiko STGK013 perfectly fits on one’s wrist, as it includes a three-fold clasp with a push-button release.

Notably, this watch does not include a bezel. It is made with dual-curved sapphire crystal and has an anti-reflective coating on its inner surface, which causes the wearer less eye strain.

To further add to the watch’s beauty, there are lines of diamonds that run along the sapphire crystal, suspending the dial in mid-air. The diamonds are embedded into the Zaratsu polished surface, which is distortion-free due to Grand Seiko’s stunning hand-craftsmanship.

There are 40 diamonds on this watch. Nineteen diamonds run along the side of the case, while two large diamonds have been a place of the 12’o clock mark, which makes the watch beautifully eye-catching.

Grand Seiko STGK013 Special :


Supple and glamorous curved form

Grand Seiko STGK013 Design

The long, flowing lines of this exquisite new case are seamless and the surfaces distortion-free so that the watch has a curved, organic feeling, as if it were hewn from nature itself. The bezel-free case and the domed sapphire crystal create a delicate arc that follows the shape of the wrist.


Case diamonds and polishing

Grand Seiko STGK013 Case

The refinement of the case is most evident when seen from the side. The diamonds are perfectly aligned and sit atop the Zaratsu polished surface which has the perfect, distortion-free finish that only this handcraft technique can deliver. While soft to the touch, every edge is sharp to the eye and catches the light in a way that is in sparkling harmony with the line of diamonds.


Elegant dial design

Dials that show the artistry of Japan.
There is a warm and uniquely Japanese elegance to the dials that derives from the a combination of the two diagonally positioned diamonds at 12 o’clock, tactile texture of the dial surface and the leaf shaped hour markers which, like the tapered hour and minute hands, are polished to ensure both their beauty and their legibility.

Grand Seiko STGK013

Mother-of-pearl dial with a deep purple color known as ’Koki-murasaki’ which has been a symbol of status since the early days of ancient Japan. Thanks to the dial’s texture and this deep color, it seems to be ever changing, each time you glance at the time, the watch brings a new sparkle to your day.



The 9S27 movement

Grand Seiko STGK013 Movement

It has a precision rate of +8 to−3 seconds a day and a power reserve of 50 hours. These high levels of performance are delivered by an 8 beat movement that is just 19.4mm in diameter and 4.49mm in height.

Grand Seiko STGK013 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
