Thinner than a human hair, the blue Parachrom hairspring patented by Rolex is crafted from an exclusive paramagnetic alloy. It is unaffected by magnetic fields and up to 10 times more resilient to shocks than traditional hairsprings. Historically, the unique blue colour of the hairspring has been a sign of prestige reserved for only the most accurate timepieces.
