Grand Seiko Sport Collection Spring Drive GMT Black-Ceramic Limited Edition SBGE039

This is the very first Grand Seiko watch to have been created by the celebrated Micro Artist Studio in Seiko’s facility in Shiojiri in the Nagano prefecture of central Japan. SBGE039 incorporated the 9R16 caliber, which is a remarkable Spring Drive caliber that offers the Studio’s trademark quality of materials and finishing.

The materials and five-piece construction are designed for strength and lightness. The inner case is made from high-intensity titanium and the outer shells and bezel are zirconia ceramic which is stronger and tougher than any other fine ceramic and seven times harder on the Vickers scale than stainless steel. The remarkable dial is inspired by the scenery of the Shiojiri Studio; is a picture of the diamond-dust sparkle of snow that shimmers in the morning light in the clear mountain air of the area, the dial glistens with a subtle and unusual beauty.
