A strategic component barely one centimetre in diameter, the Rolex Parachrom hairspring is entirely manufactured in-house and offers advantages for the precision timekeeping of the movement. A patented surface treatment enhances the regularity of the hairspring’s pulsations over time and also produces its distinctive blue colour. In watchmaking, blue hairsprings have historically been reserved for the movements of the most precise and exclusive timepieces, and the Rolex Parachrom hairspring perpetuates this tradition.
