TIP: Girard-Perregaux Manufacturered Movements

If a car wheel drives 250,000 km, its wheels will have rotated 120 million times. The balance of an oscillating movement completes 252,288,000 half rotations in a year. This means 2 billion, 522 million and 880,000 vibrations after ten years, and yet the Girard-Perregaux manufactured movement keeps on functioning. However, these movements need to be checked periodically. The enormous work carried out by the Girard-Perregaux manufactured movements is only possible thanks to the use of the best materials, the most painstaking work by the manufacturer's watchmakers and exceptional precision.
