The Generic Omega Calibre 3313 Winding Stem is a precision‑engineered aftermarket replacement component designed for the Omega Calibre 3313 automatic chronograph movement and its family variants, including Omega 3603, Omega 3202, and Blancpain 3612 – all sharing the same keyless works architecture and stem interface. Manufactured from durable steel with precision‑ground threads, this winding stem serves as the essential mechanical link between the crown and the movement’s keyless works, enabling smooth manual winding, accurate time‑setting via the crown’s pull‑out positions, and secure crown engagement.
As a reliable and cost‑effective alternative to scarce genuine OEM parts, this generic stem offers professional watchmakers and repair enthusiasts a practical solution for restoring worn, broken, or damaged original components.
Wide compatibility across Omega and Blancpain calibers – Precision‑engineered to fit Omega Calibre 3313 (automatic chronograph, Co‑Axial escapement, column wheel), Omega 3603 (automatic chronograph with GMT hand), Omega 3202 (automatic chronograph), and Blancpain 3612 – all based on the Frédéric Piguet 1285/1185 movement architecture and sharing the same keyless works and stem interface.
Three‑position crown operation – Supports three distinct crown positions: Position 1 (manual winding via the crown), Position 2 (date correction), and Position 3 (precise time‑setting with stop‑seconds/hacking function).
Durable steel construction – Manufactured from high‑grade steel with precision‑ground threads to withstand repeated winding cycles and ensure excellent long‑term wear resistance.
Seamless compatibility – Designed as a direct drop‑in fit replacement for worn or damaged original stems, requiring no modification to the movement’s keyless works.
Cost‑effective restoration – Provides a readily available and affordable alternative to scarce genuine OEM parts for routine movement overhauls, professional servicing, and daily‑wear restorations.

Always verify compatibility with your specific movement reference before purchase.
