Calibre 7140: performance and elegance
To power the 1908, Rolex’s watchmaking engineers have developed a completely new self-winding movement, calibre 7140, that allows the time to be displayed via two central hands and a small seconds hand at 6 o’clock. A number of patents have been filed for this movement, which has been entirely developed and manufactured in-house. Its cutting-edge design incorporates some major innovations from the Manufacture to guarantee exceptional performance, including the Syloxi hairspring in silicon, Chronergy escapement in a nickel-phosphorus alloy – both of which are resistant to strong magnetic fields – and Paraflex shock absorbers, which protect the oscillator and escape wheel from any shocks to the watch.
