This Seiko SQ men’s watch is a 36mm round timepiece featuring a brown dial and a silver-tone stainless steel case, complete with a day-date display and non-numeric hour markers. This unit is pre-owned and offered strictly for parts or repair. It shows scratches on the case and crystal, and the movement is not currently running; a new battery will not restore operation. Specifically designed for the Seiko 7546-8139 family, it serves as a highly relevant donor for restoration projects or spare-part needs.

Why this donor watch stands out for restoration and parts projects:

• Authentic compatibility: Built to fit Seiko 7546-8139 models, allowing for seamless part swaps when restoring or repairing that lineage.
• Targeted parts value: The case and crystal are visible salvage opportunities for preserving the original finish and fit of a 7546-8139 restoration.
• Clear condition for parts work: With the movement non-functional, you can focus on diagnosing and replacing specific components without risking a working unit.
• Useful for collectors and hobbyists: A genuine Seiko donor unit offers authentic dimensions, finish, and aesthetics to support authentic restorations or parts inventories.
