Original Seiko spare part – setting lever screw (押鳥捻) for the Seiko "Solar" (ソーラー), from unused old stock (NOS) (1 piece)

What is offered is a single piece, taken from an original "Seiko Watch Parts" dealer bag (printed with "[ID according to bag] (ソーラー)" and "押鳥捻").

The setting lever screw secures the setting lever (押鳥 / おしどり, setting lever) in the keyless works. In movements with a screw-type setting lever, this screw is loosened to release the winding stem and remove the crown. A small but essential fastening part; it is often lost during revision or its thread becomes damaged – a genuine, suitable replacement part is therefore sought after.

According to the movement imprint, the designation "Solar" (ソーラー) refers to an early, mechanical Seiko model – not the modern, solar-powered Seiko quartz watches (from 1977 onwards). Original spare parts for these early Seikos are now rarely available, which makes this part particularly relevant for watchmakers and collectors.

The part is unused and in very good original condition; due to storage, at most minor, purely cosmetic marks may be present, which do not affect functionality.

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 with the target caliber or setting lever; assembly should be carried out professionally.
