Seiko 5 watch case, marked for a 21 jewel movement, a neat find for custom watch builders, restorers, and vintage enthusiasts. It brings classic Japanese design straight to your workbench.
The seller notes no noticeable scratches or stains, though this is listed as a junk piece, sold as-is for parts or repair rather than as a working watch.
The Seiko 5 lineup debuted in the 1960s and quickly built a worldwide reputation for durability and practical design. The "5" represented five key attributes: automatic winding, a single window for day and date, water resistance, a recessed crown, and a sturdy case. Original components from older models remain popular around the globe for custom builds and period-correct restorations.
