This is a generic sliding pinion (clutch wheel) for the Rolex Caliber 2235 automatic movement, corresponding to part number 2235-205. As a key component of the keyless works, it mounts on the winding stem and works with the winding pinion to switch between manual winding and time‑setting modes. When the original part becomes worn, stripped, or damaged, causing the crown to spin freely or setting to fail, this aftermarket replacement offers a cost‑effective solution to restore movement function.
Generic Replacement – Designed for Rolex 2235 movement; non‑original but matches OEM dimensions and tooth geometry.
Keyless Works Core – Slides on the winding stem to switch between winding and setting modes, working with the winding pinion and clutch mechanism.
Precision Machined – Made of quality steel with accurately cut teeth and sliding surfaces for smooth, reliable engagement.
Cost‑Effective – More affordable than genuine parts, ideal for routine service.
Direct Replacement – Same installation as the original; no movement modification required.
