Heritage Collection Annual Accuracy Quartz SBGX361
The 33mm quartz “Skyflake,” evoking winter snow reflecting the blue sky
Features
Visible from the Shinshu Watch Studio, home to all Grand Seiko quartz watches, the Hotaka mountain range remains blanketed by snow for several months each winter. Fierce winds sculpt the alpine snow into intricate patterns, inspiring the distinctive dial design. The dial pattern of the SBGX361 is inspired by images of wind-swept snow reflecting the blue sky on a clear, crisp day.
The watch is presented in a 33mm x 9.1mm case, the slimmest and smallest in diameter of any Grand Seiko 9F creation to date, made possible by the new Calibre 9F51.
