Genuine Seiko spare part – 押鳥捻（おしどりねじ）/ Setting Lever Screw for the Seiko "Merit", from new old stock (NOS) (1 piece)

A single piece is offered, taken from an original "Seiko Watch Parts" dealer bag (printed with "6M (メリット)" and "押鳥捻").

The setting lever screw secures the setting lever (押鳥 / おしどり) in the keyless works. In movements with a screw-type setting lever, this very screw is loosened to release the winding stem and remove the crown. A small but essential fastener; it is often lost during overhaul or the thread suffers – a genuine, fitting spare part is therefore sought after.

The designation "Merit" (メリット) refers to an early Seiko model series from the post-war period (1950s). Original spare parts for these early Seikos are rarely available today, which makes the part particularly relevant for watchmakers and collectors.

The part is unused and in very good original condition; due to storage, only minor, purely cosmetic traces are possible, which do not impair the function.

Manufacturer: Seiko (K. Hattori & Co. / Seikosha, 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
Setting lever screws are caliber-specific (thread diameter/pitch, length, head shape). Before installation, please compare the dimensions and fit on the target caliber or setting lever; installation should be carried out professionally.
