SBGM253 celebrates the 25th anniversary of the Calibre 9S mechanical movement, with a design that depicts the clear blue sky as seen from the top of Mt. Iwate, visible through the windows of the Grand Seiko Studio Shizukuishi where this watch is meticulously crafted.
This timepiece is powered by the GMT self-winding Calibre 9S66 movement, which runs for approximately 72 hours when fully wound.
