I’m selling a Seiko Mechanical HAYASHI SEIKI SEIZO 100th Anniversary Limited Edition, an extremely rare JDM (Japan Domestic Market) model that is very hard to find on the market right now. This watch was produced in limited numbers to commemorate the 100th anniversary of Hayashi Seiki Seizo, a company that manufactures premium genuine components for Seiko. Condition: Pre-owned, with a few minor scratches from regular use, but overall still in very good condition. Case size: 40mm | Lug width: 20mm Movement: Seiko 6R15, running with a deviation of about +15 seconds per day. Dial, hands, and indices: The dial is uniquely decorated with an elegant repeating “H” pattern and features the large Hayashi 100th Anniversary logo at 6 o’clock. The dial remains in excellent condition and reflects light beautifully. Caseback: Very special and artistic design, prominently featuring the finely finished Hayashi logo. Crystal: Dual-sided AR-coated sapphire – very clear, scratch-free, and easy to read even in low-light conditions Strap: Includes two sets of genuine Seiko leather straps: an unused plain brown leather strap and the original crocodile-pattern strap. The inner lining of the original strap shows some peeling due to age, but it remains structurally strong and can still be used for a long time. Fits wrists from approximately 15–20cm Included accessories: Limited edition box featuring the Hayashi logo The watch itself Warranty card Original leather strap (2 set) This is a rare and highly collectible piece for Seiko fans and JDM watch enthusiasts!
