Girard Perregaux Tourbillon Chronograph
前后 Around 1880, Constant Girard conducted in-depth research on the practicability and accuracy of time measurement tools, and produced a self-produced pocket watch with a femtosecond function. Nine years later, he introduced the Sanjinqiao Tourbillon technology, which won the Paris World Expo Award. This year, Constant Girard has completed a bigger challenge, integrating all the above complex functions to make the timing accuracy up to 1/6 seconds, which can not help but admire Girard Perregaux’s technical strength.
Chasing hands and femtoseconds are Girard-Perregaux’s expertise, but it is the first time to integrate the tracking hands, femtoseconds and tourbillon. On the basis of retaining the traditional hand-tracing function, this watch adds a femtosecond system with a rotation speed of 1 revolution per second at the 9 o’clock position, which improves the timing accuracy of the watch.
