The Rolex Calibre 3135-220 Setting Lever (also referenced as part number B3135-220-Y1) is a genuine OEM component manufactured in Switzerland for the legendary Rolex Calibre 3135 self-winding automatic movement and its no-date variant Calibre 3130. As a critical element of the keyless works system, this precision-engineered stainless steel setting lever works in coordination with the spring for setting lever (No. 3135-225) and the yoke for setting wheel to transmit axial motion from the winding stem to the sliding pinion, enabling the selection of winding and time-setting positions via the crown. This exact-match drop-in replacement part is essential for professional watchmakers restoring worn or damaged original components to factory operational standards.
Genuine OEM manufacturing – Authentic Rolex part crafted in Switzerland to original factory tolerances, ensuring perfect fit, function, and long-term reliability
Keyless works precision – Forms an integral part of the winding and setting mechanism, translating crown position changes into distinct operational modes（winding vs. time-setting）in coordination with the setting lever spring（No. 3135-225）and yoke for setting wheel（No. 3135-266）
Extensive caliber compatibility – Designed for Calibre 3135（date version）and cross‑compatible with Calibre 3130（no‑date version）; also compatible with other movements within the 31xx‑series automatic family including 3155 and 3175
Stainless steel construction – Manufactured from durable stainless steel for excellent mechanical strength and long‑term wear resistance
Drop‑in replacement fit – Engineered as an exact-match substitution for worn, damaged, or lost original components without modification or additional adjustment
