The Rolex Calibre 2135-220 Setting Lever is a genuine OEM component manufactured in Switzerland for the iconic Rolex Calibre 2135 self‑winding automatic movement, widely used in Lady‑Datejust and midsize Oyster Perpetual Date models from the 1980s and 1990s. As a core element of the keyless works system, this precision‑engineered setting lever controls the pull‑out and push‑in positions of the winding stem, enabling seamless switching between winding, quickset date adjustment, and time‑setting modes via the clutch wheel. This exact‑match, drop‑in replacement part is essential for professional watchmakers restoring worn, damaged, or missing original components to preserve the legendary reliability of the Calibre 2135.
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, time‑setting, and quickset date adjustment).
Quickset date compatibility – Works in coordination with the jumper for setting lever (No. 2135‑230) to enable the independent quickset date correction function, a major upgrade over older calibers.
Compact movement integration – Engineered specifically for the compact 20.00 mm diameter Calibre 2135, providing the reliable keyless works operation that contributed to the movement‘s industry‑leading COSC pass rate.
Drop‑in replacement fit – Engineered as an exact‑match substitution for worn, damaged, or lost original components without modification or additional adjustment.
