Details of the Rolex Cal 9001 movement:
Developed and manufactured in-house, calibre 9001 is one of the most complex movements ever created by Rolex watchmakers.
A selector wheel on the outside edge of the movement ensures the interaction of the movement and the bezel of the watch to set the functions.
CHRONOMETRIC PRECISION
Calibre 9001 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. The oscillator has a blue Parachrom hairspring patented and manufactured by Rolex in an exclusive paramagnetic alloy.
SINGULAR RELIABILITY
The architecture behind the 9001, like that of all Perpetual movements at Rolex, makes it singularly reliable.
The oscillator is fitted between high-performance Paraflex shock absorbers, developed and patented by Rolex, that offer 50 per cent greater resistance to shocks. It is held firmly in place by a height-adjustable traversing bridge. The Saros annual calendar and the Ring Command setting system are also designed to be exceptionally robust.
SELF-WINDING BY PERPETUAL ROTOR
Calibre 9001 is fitted with a self-winding mechanism featuring Rolex's Perpetual rotor, which ensures continuous winding of the mainspring by harnessing movements of the wrist to provide a constant source of energy.
