Product Description

The Generic IWC Calibre 80111 Winding Stem is a high-quality aftermarket replacement component specifically engineered for the IWC-manufactured 80111 automatic movement, a robust in-house caliber featuring the patented Pellaton bidirectional winding system. This precision-machined stainless steel stem serves as the essential mechanical link between the crown and the movement’s keyless works, enabling smooth manual winding and precise time-setting with hacking seconds functionality.

Features & Function

Precision-engineered compatibility – Specifically designed to fit IWC’s in-house Calibre 80111 automatic movement, a compact 30.00 mm diameter × 7.30 mm thick movement with the patented Pellaton bidirectional pawl-winding system, featuring shock absorber device and 28,800 vph frequency.

Two-position crown operation – Supports manual winding (position 1) and precise time-setting with stop-seconds/hacking function (position 2) via the crown’s pull-out positions, ensuring accurate time synchronization.

Durable stainless steel construction – Manufactured from high-grade stainless steel with precision-ground threads (standard Tap 10 / 0.90 mm thread diameter) to withstand repeated winding cycles and ensure excellent long-term wear resistance.

Drop-in replacement fit – Engineered as a direct-fit substitution for worn, broken, or damaged original stems, requiring no modification to the movement’s keyless works.

Cost-effective restoration – Provides a practical, readily available alternative to scarce and expensive genuine OEM parts for routine movement overhauls, professional servicing, and daily-wear restoration.

Applications

Replacement of worn, broken, or damaged winding stems during professional servicing of IWC Calibre 80111 watches, including Ingenieur Automatic references (IW323305, IW323311, IW323401, etc.), Aquatimer Vintage 1967 (IW323101), Portuguese Vintage Collection and Replica Edition references, and other IWC models equipped with the 80111 movement.

Professional watch repair centres and independent watchmakers performing movement overhauls that require disassembly of the keyless works and crown stem replacement.

Restoration of pre-owned IWC timepieces where original stem threads are stripped, the stem is bent or broken, crown function is compromised, or the watch exhibits symptoms of worn winding mechanism.

Frequently Asked Questions

Q1: Is this winding stem an authentic genuine IWC part?
No, this is a generic aftermarket replacement product, not manufactured by IWC. It is designed to meet the compatible specifications for the Calibre 80111 movement and should not be confused with genuine OEM components. For routine servicing and daily-wear restoration, a quality generic stem from a reputable supplier offers a practical solution; for absolute factory originality, genuine OEM parts are recommended.

Q2: Which calibers is this generic stem compatible with?
This generic stem is specifically designed for the IWC Calibre 80111 automatic movement, which is a reduced-height version of the 80110 caliber (produced from 2007–2011). It is not compatible with other IWC calibers such as the 80110 (original height variant), 89365, or 50000-series unless confirmed by the movement reference. Always verify compatibility with your specific movement reference before purchase.

Our replacement stems are manufactured from high-grade stainless steel with precision-ground threads (standard 0.90 mm Tap 10) and are designed to meet the mechanical specifications for reliable winding and time-setting functions. For routine servicing, daily-wear restoration, and independent repair work, a quality generic stem from a reputable supplier offers a practical and reliable solution; for absolute factory originality, genuine OEM parts are recommended.
