Vacheron Constantin caliber 1120
Developed and crafted in harmony with Geneva’s most rigorous Fine Watchmaking traditions, caliber 1120 beats at a frequency of 2.75 Hz (19,800 vibrations/hour) and is endowed with an approximately 40-hour power reserve. Both its finishing and its construction testify to a wealth of fine workmanship. Not only are the smooth surfaces of the movement adorned with a meticulously executed “Côtes de Genève” motif, but all their sharp angles are chamfered and then hand-polished. Such is also the case with the screw heads.
