Inspired by the changing colours of Mount Iwate at dusk, the Grand Seiko Heritage Collection Mount Iwate – Autumn Dusk SBGW303 captures one of nature’s most striking moments in a beautifully executed limited edition. Created exclusively for the European market, the watch blends Grand Seiko’s celebrated design language with the subtle beauty of the Japanese landscape. The 36.5mm stainless steel case showcases the sharp lines and mirror-polished surfaces of the iconic 44GS design, finished using Grand Seiko’s renowned Zaratsu polishing technique. Its standout feature is the textured dark green dial, featuring the signature Mount Iwate pattern inspired by the ridges of the mountain visible from the Grand Seiko Studio Shizukuishi. Adding to its distinctive character, the gold Grand Seiko logo represents the autumn moon rising over Mount Iwate, contrasting beautifully against the rich green dial. Faceted hands and indexes ensure exceptional legibility while reflecting light from every angle. Powering the watch is the manual-winding Calibre 9S64, an in-house movement offering a 72-hour power reserve and renowned for its precision and reliability. Limited to 400 pieces this being 265. It is sold as a full set with its original Grand Seiko box, original warranty card, instruction manual, cloth and hangtag, as well as its original purchase receipt. This watch was first sold in the UK in November 2025.

The sustainable choice

Buying pre-owned watches and jewellery is a more sustainable choice as it gives existing pieces a longer life. Instead of mining or using new materials, you’re extending the story of beautifully crafted items that already exist, reducing waste, preserving resources, and celebrating timeless craftsmanship in the most responsible way.
