The Generic Piaget Calibre 9P2 Winding Stem is an aftermarket replacement component designed for the legendary ultra-thin hand-wound movements Calibre 9P2 and its predecessor 9P. This stem serves as the critical mechanical link between the crown and the movement‘s keyless works, enabling manual winding and precise time-setting.
Two-position operation – Supports winding (position 1) and time-setting (position 2)
Wide compatibility – Fits Calibre 9P2 and original Calibre 9P (same keyless works)
Stainless steel construction – Durable, corrosion-resistant, long-lasting
Direct replacement – Drop-in fit, no modification required
Cost-effective – Affordable alternative to scarce OEM parts
