The 1908 is equipped with calibre 7140, a movement wholly developed and manufactured by Rolex, unveiled in 2023. A distillation of technology, this self-winding mechanical movement delivers outstanding performance in terms of precision, power reserve, convenience and reliability. Calibre 7140 demonstrates carefully finished aesthetics, notably on the bridges, which feature Rolex Côtes de Genève – a decoration that differs from traditional Côtes de Genève for the slight polished groove between each band.
Calibre 7140 incorporates the patented Chronergy escapement, which combines high energy efficiency with great dependability. Made of nickel- phosphorus, this escapement is resistant to strong magnetic fields. The movement also includes the patented Syloxi hairspring and its power reserve extends to approximately 66 hours.
