Nature and architecture inspire a classic Grand Seiko design

Grand Seiko's rich tradition of pulling inspiration from the natural world and Japanese culture is expressed on the dial of SBGJ271. The distinct texture and white color evoke the reflection of snow-covered trees on lacquered wooden floors that are often found in traditional Japanese architecture. This light dusting of snow is known as yukigesho.

Classic in its form and function, the the stainless steel case of SBGJ271 measures 39.5mm in diameter, and has a vintage-inspired box-shape sapphire crystal.

Caliber 9S86 runs at 36,000 bph, has a 55-hour power reserve, and an accuracy rating of +5/-3 seconds a day. Through the utilization of MEMS and through the development of Spron alloys for the mainspring and hairspring, Grand Seiko was able to create high frequency movements that could maintain a 55-hour power reserve while running at a high frequency.
