(Listing due to home organization) (I am also listing on other flea markets, so this may end without notice. Thank you for your understanding.) (Purchased from the official online shop in May 2025. I am listing it as I don't have many opportunities to use it. The strap has been replaced with a different official one and adjusted to 17.5cm, but the tools and spare strap parts are still present and will be included. The condition is very good, with few uses. Although it's a personal inspection, I don't see any scratches and will classify it as "like new." Operation has been confirmed, and all manuals are included. Please see photos for details.) (The retail price was 36,850 yen, and I recall the official strap costing in the 6,000 yen range. Therefore, I believe my price is quite a good deal, so please consider it.)
