It is fitted with a Parachrom hairspring, offering greater resistance to shocks and to temperature variations.
Mechanical automatic self-winding Rolex caliber 3185 movement is rhodium-plated, with oeil de perdrix embellishment, a straight-line lever escapement, and a monometallic balance that's adjusted to temperatures and 5 positions. It includes a self-compensating free-sprung Breguet balance spring, Microstella regulating screws, and a central hacking seconds mechanism.
This mechanism oscillates at a frequency of 28,800 vhp (4Hz).
