Inspired by Japan's Tsuyu rainy season, the U.S. Exclusive SBGW311 by Grand Seiko embodies the lush greenery surrounding Mt. Iwate. A modern interpretation of the 1967 44GS, this timepiece features a stainless steel bracelet with a three-fold clasp. Hand-assembled at Grand Seiko Studio Shizukuishi, the watch houses the Caliber 9S64, a mechanical manual-winding movement offering a remarkable 72-hour power reserve and an accuracy of -3 to +5 seconds per day. The craftsmanship reflects Grand Seiko's dedication to precision, drawing inspiration from the natural beauty of rice fields and forests nurtured by the seasonal rain.
