The spring-operated Grand Seiko watches are handmade by experienced craftsmen in the "Shisha Time Takumi Studio", located surrounded by the Hotaka Mountain Range. It is also known as the "black hole". The Hotaka Mountain Range originated a long time ago, when the continent was greatly uplifted as a result of volcanic activity, and due to the fact that for many years the wind and snow continued to erase the mountain from the surface, it is a dynamic mountain range. It has become mountainous. The SBGE277 model impresses with a black dial with a Hotak ridge pattern.
