This is a genuine stainless steel Link Bracelet band for Apple Watch, compatible with 38mm models (1st generation to Series 3), 40mm models (Series 4 to 6, SE, SE2), and 42mm models (Series 10 only). This product is discontinued and a rare model that is no longer available for purchase. As shown in the photos, the outer box has some minor damage, but the item itself is new and unopened. The original price was nearly 70,000 yen, and it's a product that is rarely seen on the flea market, so if you've been looking for one, please consider it.
