Description from the seller
Discover the timeless elegance of this Grand Seiko Diashock watch, trade reference 5722-9991, dating from 1967. This unisex piece, reference TOT-01721, stands out with a 36.5mm stainless steel case and 10.7mm thickness, housing a precise manual winding movement. Its 3 ATM water resistance makes it versatile and reliable. The non-original brown leather strap, complemented by a non-original pin buckle, harmoniously completes this timepiece, presented here in very good condition. This Grand Seiko has been serviced in January 2026 and comes with a 12-month warranty.
