Last year, Jacob & Co. turned watchmaking on its ear by introducing the Twin Turbo Furious, a grand complication that combined of a twin accelerated triple axis sequential tourbillon, a minute repeater and a mono-pusher chronograph.
To take the Twin Turbo Furious, Jacob & Co. has done what comes naturally to the brand – add baguette gems to this spectacular timepiece. The case of this timepiece is in 18K White Gold and is set with 344 Baguette Diamonds (~16.7cts). Even the clasp of this timepiece is set with 22 Baguette Diamonds (~1.4cts).
Jacob & Co.’s Twin Turbo Furious, which was three years in development, sets itself apart from this distinguished lot, incorporating two accelerated triple axis sequential tourbillon into its striking design. The tourbillons fly their courses at a rhythm of one rotation in 24 seconds on the first axis, in eight seconds on the second, and in 30 seconds on the third. The tourbillon cages housing the regulating organs sweep over all the positions in half a minute and compensates the effects of gravity on the chronometric precision of the movement.
The benefit of the connection between the two tourbillon cages is to stabilize the entire system. In case of impact, if either one of the two tourbillons were to be affected by the shock, the other would instantly compensate the potential discrepancy and maintain the movement’s perfect accuracy.
Minute repeaters are also the most difficult complication for watchmakers to conceive. Nevertheless, Jacob & Co. sought to push the boundaries of what was considered technically feasible when bringing the Twin Turbo Furious to life. In order to simplify the aural indication of time, the Twin Turbo Furious chimes every ten minutes, a so-called decimal repeater that is very rare in high watchmaking.
The power reserve is displayed on the dial side at 6 o’clock. Thanks to an ingenious planetary system comprising a differential gear mechanism; the hand points to a full power reserve on the left, then moves to the right as the 50 hours of reserve winds down. The watch is wound up through the crank placed on the crown at 3 o’clock.
With the Twin Turbo Furious, Jacob & Co. goes even further by adding a very specific chronograph function. Embodying the Swiss House’s determination to always seek new solutions or to create never-before-seen functions, the Twin Turbo Furious is equipped with a “reference time” indicator. The reference time indicator offers instant reading inspired by the timekeeping panels used in motor racing; with each lap, the panels displayed on the side of the track would tell the drivers the time difference between their time and the lap reference time.
The Twin Turbo Furious display is located in the center of the dial, which indicates the difference in seconds in comparison to a reference time.
