With SBGH345, innovation, precision, and timeless design converge to create a timepiece that stands as a testament to the artistry of Grand Seiko.
The 40mm diameter, 13.3mm thickness, and 46.2mm case length offer a perfect balance of sophistication and presence on the wrist. The multi-faceted 44GS case is made of Ever-Brilliant Stainless Steel. This robust material boasts a PREN (Pitting Resistance Equivalent Number) value 1.7 times higher than standard stainless steel, setting a new standard in corrosion resistance.
Inspired by the morning sun as it falls upon the side of Mt. Iwate, the scarlet dial of SBGH345 adds a touch of allure, complemented by multi-faceted indexes, razor-sharp hands, and the intricate Mt. Iwate pattern. These details are visible through a dual curve sapphire crystal.
At its heart is the 9S85 Caliber, a Hi-Beat 36000 movement with 37 jewels and an accuracy of +5 to -3 seconds per day (when static). This high-frequency automatic movement has an approximate 55-hour duration.
