Seiko Spare Part – Yoke Spring for Lady Seiko (Women's) (1 piece) – NOS

Original Seiko Yoke Spring (カンヌキ押エ / Yoke Spring) from new old stock (NOS) for the Lady Seiko (レディーセイコー) – Seiko's ladies' line. Offered is a single piece, taken from an original "SEIKO WATCH PARTS" pack ("12 pcs."); the box is stamped "新" (= "new").

The yoke spring belongs to the keyless works: it presses or positions the yoke (カンヌキ / yoke), which shifts the clutch (つづみ車 / sliding pinion) between winding and hand setting, and ensures its defined position and return.

The part is unused; due to storage, only minor, purely optical traces are possible, which do not impair the function.

Note on assignment: Before installation, please compare the shape, dimensions, and fit with the required part or the Lady Seiko caliber.

Manufacturer: Seiko (K. Hattori & Co., Japan).

Warranty (used) This is an original part (NOS) stored for decades. The limitation period for claims for defects (statutory warranty) is 12 months from delivery.

Note Before installation, please compare the shape, dimensions, and fit with the required part; assembly should be carried out professionally.
