Richard Mille RM UP-01 Ferrari is the world’s thinnest mechanical watch. Their titanium case is only 1.75 millimeters thick (two credit cards stacked together), 0.05 millimeters thinner than the previous record holder Bvlgari Octo Finissimo Ultra. The watch mechanism was developed by Richard Mille together with the Audemars Piguet Le Locle laboratory. It operates at a frequency of 28,800 vibrations per hour and provides a power reserve of 45 hours.
