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 Quenttin?s 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.

The manually wound mechanical movement, entirely manufactured in Switzerland, is positioned vertically and oscillates at a rate of 21,600 vibrations per hour. This Tourbillon has been replaced in its vertical position according to the original design of its inventor Abraham Louis Breguet, who developed the concept to compensate for the effect of terrestrial gravity in timepieces which at the time were pocket watches.

The Quenttin’s movement is revolutionary in the sense that all the wheels do not revolve around a central arbour, but around several arbours aligned horizontally, like the gearbox in a car engine. The time, hours and minutes, as well as the power reserve, are read on cylinders and not by means of hands.

This world premiere with a one-minute vertical tourbillon and 31 days power reserve is one of the most technical Jacob & Co. The exclusive manually wound Jacob & Co with seven spin barrels highlight this watch’s uniqueness. The 45 mm timepiece boasts a complex transparent dial, revealing parts of the movement for an added touch of intimacy.
