Authentic vintage Grand Seiko 43999 "Self-Dater" manual-wind men's watch (defective/for repair). The watch is non-functional; it lacks a crown, so it cannot be wound, and its condition cannot be fully assessed. The crystal shows signs of aging, and the dial exhibits oxidation. The case back is stuck tight; a watchmaker attempted to open it but was unsuccessful, and the cause remains unknown. There are several deep scratches on the case back—it is unclear if these resulted from previous attempts to open it. The watch is guaranteed authentic. Sold "as-is"; please carefully examine the photos to verify the item's condition.

Buyers are advised to purchase this item for repair or parts purposes. As it is a high-value item with a serious malfunction, no returns or claims will be accepted after the sale.
