Envisioning Mt. Iwate as the rainy season takes shape in early Summer. Tsuyu is the rainy season that begins in early summer in Japan. In Iwate, lush green can be seen surrounding the grand Mt. Iwate in the distance, with the rain bringing life to rice fields, forests, and other natural beauty in abundance in the region. This serves as the source of inspiration for the U.S. Exclusive SBGW311. The 44GS, released in 1967, was the first to define the Grand Seiko Style and has evolved into a modern interpretation with contemporary practicality. The SBGW311 embodies Grand Seiko Style in a stylish mid-size case at 36.5mm diameter with manually wound mechanical Caliber 9S64, providing the watch a 72-hour power reserve despite its compact size.
