Jacob & Co. Quenttin Tourbillon

The Quenttin Tourbillon is the first timepiece created with a 31-day power reserve and a one-minute vertical tourbillon. One of the most technical of timepieces, the Quenttinʼs movement is also revolutionary in that all wheels are positioned around several axles lined up in a horizontal position-similar to the gearbox of a car-instead of around one central axle – all visible through a complex transparent dial.
