► SELLER'S DESCRIPTION
Up for sale is a Rare Vintage Seiko Kinetic 5M23-6B70 men’s sports dress watch, a Japan Domestic Market (JDM) model from the 1990s. Featuring Seiko’s innovative Kinetic technology, this model combines the convenience of quartz accuracy with energy generated through wrist movement, representing one of Seiko’s most important technological developments of the era. Its attractive two-tone design and versatile styling make it equally suitable as a dress watch or everyday wearer.
The watch is being sold for parts and repair. It is currently not running and requires servicing in order to be returned to proper operating condition. The exact issue has not been diagnosed, and no internal inspection has been performed, so the cause of the problem is unknown.
All parts of the watch are original, including the original Seiko signed two-tone stainless steel bracelet and clasp.
The watch is in good physical condition with signs of use and age consistent with a vintage timepiece. The photos best describe its physical condition and should be reviewed carefully before purchasing.
