Discover the timeless elegance of this Grand Seiko Diashock watch, commercial reference 5722-9991, dating from 1967. This unisex piece stands out with its 36.5 mm steel case and 10.7 mm thickness, housing a precise manual movement. Its 3 ATM water resistance makes it versatile and reliable. The non-original brown leather strap, enhanced by an equally non-original pin buckle, harmoniously completes this timepiece, presented here in very good condition. This Grand Seiko was serviced in January 2026 and comes with a 12-month warranty.
