Unveiled in 2026 and exclusive to the Yacht-Master II, calibre 4162 is a chronograph movement with a countdown function, entirely developed and manufactured by Rolex.
The new-generation Yacht-Master II is equipped with calibre 4162, an evolution of calibre 4161 that was fitted on the model’s predecessor. This self-winding mechanical movement delivers outstanding performance, particularly in terms of precision, power reserve, convenience and reliability.
The countdown function is engaged by a robust mechanism with a column wheel and vertical clutch, allowing an instantaneous and extremely precise start. Calibre 4162 also incorporates a number of the major innovations that Rolex has brought to its movements, including the Chronergy escapement. Thanks to the architecture of its barrel and the superior efficiency of its escapement, the power reserve of this movement extends to approximately 72 hours. Calibre 4162 demonstrates carefully finished aesthetics, notably bridges decorated with Rolex Côtes de Genève and a cut-out oscillating weight.
