Only accessible in Europe, the 'Mount Iwate Autumn Dusk' reconciles the classic aesthetics of the company's 44GS selection with modern manual-winding 3-hand movement technology. This special watch reflects the distinct Japanese sense of beauty, with its signature interplay of light and dark.

This watch, from the Grand Seiko Heritage Collection, is a limited edition with a 36.5mm green dial. It has a striking "Mount Iwate" pattern, capturing the crags of the mountain peak visible from the Shizukuishi studio where it is hand-crafted. Its texture evokes the atmosphere of Mount Iwate at dusk, showcasing an iridescent sheen that catches the light.

The 'Mount Iwate Autumn Dawn' draws from Taro Tanaka's 1967 Grammar of Design, a concept designed to give Grand Seiko watches a distinct look with sharp edges, large Zaratsu polished surfaces, slim flanks, an almost-invisible bezel, and dial elements with a clear distinction. All these elements are delicately crafted into a case that offers a classic look, measuring 36.5mm in diameter and 11.5mm in depth.

Crafted for everyday wear, the SBGW303G features a water resistance of 100m, built-in 9S64 movement running at 4Hz, and a substantial 72-hour power reserve. Its accuracy ranges from +5 to -3 seconds per day and provides you with reliable performance.

The Grand Seiko SBGW303G Gents Manual Wound Watch is finished with a secure three-fold clasp and push-button release bracelet to ensure a comfortable fit. Plus, an extra strap is included for versatile styling options. This exclusive European edition is limited to only 400 units, each engraved with an individual number on the case back.
