Rolex Movement (photo: Rolex/Jean-Daniel Meyer)

The movements used in men's Rolex models are equipped with a blue Parachrom hairspring patented by the watchmaker. The alloy used for the hairspring consists of niobium, zirconium and oxygen. It is insensitive to magnetic fields and able to compensate for temperature variations, allowing it to remain precise even in less than ideal conditions. Rolex introduced the Syloxi hairspring, made using silicon, in 2014 for the lady's models.

High performance lubricants, gold Microstella nuts and a traversing balance bridge also help make Rolex's in-house movements oscillate at a frequency of 28,800 beats per hour. In 2005, they introduced the Paraflex shock absorber that doubled the shock absorption of previous movements. The watchmaker continues to integrate their production processes, giving them more control over the quality and precision of their timepieces.
