Seiko Chorus Calendar – Dial Holding Screw (文字板止金) – NOS Watch Part – (1 Piece)

Original Seiko dial retaining screw from unused new old stock (NOS) for the Seiko "Chorus Calendar" line (Japanese: 文字板止金, mojiban-tomegane).

This small retaining part secures the dial to the movement – a functional original part, often missing during restorations, for the corresponding Chorus Calendar models.

The Seiko Chorus was a vintage ladies' line from Seiko, predominantly from the 1960s and early 1970s (square/round steel or gold-plated cases, manual-winding calibers such as 2104/2118); "Calendar" refers to the date versions of this line.

The parts come from an original Seiko factory bag; the price is per piece.
