The hairspring is one of the most important components of the mechanical watches, which has great effect on the movement of the watches. Each brands are continuing to develop and improve the performance of the hairspring. Firstly I will introduce the famous Parachrom hairspring to you.
The hairspring is a very thin spring to drive the balance wheel to swing back and forth. So the performance of the hairspring directly influences the precision of the wristwatches. But the hairspring is easy to be effected by the outside world which is including the temperature, magnetism, shocking and vibration. From Oyster Perpetual to Day-Date, all the male watches are equipped with Parachrom. The Rolex Day-Date copy with gold case has used the great Parachrom hairspring.
The Parachrom hairspring was firstly used in 2000, basically breaking through all the technical problems of hairspring. The Parachrom hasn’t contained any iron, eliminating magnetic field effects. The perfect fake Rolex Oyster Perpetual has equipped the Parachrom too.
