Product Details

The TimeWriter II Chronographe Bi-Fréquence 1.000 appears to contradict the laws of pure science. A childhood memory of a rolling hoop inspired Barto Gomila to develop an innovative chronograph mechanism that has been created under the TimeWriter scheme by the master watchmakers of Montblanc’s Manufacture in Villeret. Whereas a frequency of 500 Hz is generally considered physically necessary to capture the thousandth of a second in a mechanical watch, this genuine chronograph accurately measures down to the 1/1,000th of a second with a frequency of only 50 Hz. With minimised wear and friction, the watch sets new standards in precision, regularity and long-lasting power reserve.
