The Genuine Rolex 2235-205 Sliding Pinion (also referred to as a Clutch Wheel) is an authentic OEM spare part, specifically engineered for the high-precision Rolex Calibre 2235 automatic movement. As a core component of the watch’s keyless works system, this part interacts with the winding stem to safely lock and unlock the automatic winding mechanism when the crown is used for manual winding or time-setting. This original factory component is essential for watchmakers performing professional overhauls to restore smooth crown operation and the movement’s integrated safety features.
Genuine OEM Component – An authentic, factory-original Rolex spare part (Ref. 2235‑205), guaranteeing a perfect fit and uncompromised reliability.
Critical Keyless Works Part – As a sliding pinion, it securely transfers manual winding energy to the gear train or seamlessly disengages to allow for precise time-setting.
Integrated Safety Clutch – Functions as a safety mechanism, preventing potential over‑winding and protecting the movement’s delicate wheels from excessive force.
Directive for Service – This part is recommended for replacement during a full service to eliminate wear-related sticking or slipping and to maintain the crown’s crisp tactile feel.
