THE COMPLICATIONS AND FEATURES
IofV
THE V16 ENGINE-BLOCK AUTOMATON
This one-of-a-kind automaton is made of a single, very large block of transparent sapphire, in which 16 cylinders are drilled. They house 16 titanium pistons. They're driven by an achievement of watch manufacturing : a single-axis crankshaft. It is one of the longest, most elaborate and most delicate watch parts ever crafted. When the automaton is activated, the crankshaft spins and all 16 cylinders move up and down. The engine block is connected to a set of 16 exhaust manifolds. After the pusher within the crown is activated, the automaton sequence lasts 20 seconds.

THE 30-SECOND FLYING TOURBILLON
Gravity has a naturally negative impact on a movement's accuracy. By putting its escapement into a constant spin, the tourbillon counteracts this natural defect. The faster the rotation, the better the accuracy. In Caliber JCAM55, this rotation takes 30 seconds, twice as fast as the ubiquitous one-minute period. The tourbillon carriage being held only by its base, with no upper bridge, makes it a flying tourbillon.

THE RETROGRADE, JUMPING HOURS, AND RETROGRADE MINUTES
Both the hour hand and the minute hand are retrograde. After they complete a 270-degree arc, when they finish their own cycle, they jump back to zero and start anew. What's more, the hour hand is jumping. Every 60 minutes, the blue hand jumps to the next hour and stays there until the next one is up.

THE DOUBLE POWER RESERVE INDICATOR
A unique feature in contemporary watchmaking, the Bugatti Tourbillon displays the power reserve of its automaton. The engine block automaton can execute an incredible 20 consecutive animation sequences on a single, full wind. The remaining autonomy is indicated by the smaller hand in the Power Reserve counter. Caliber JCAM55's overall power reserve of 48 hours is indicated by the larger, red hand in the same subdial.

THE INVISIBLE SETTING
The setting of the Jacob & Co. Bugatti Tourbillon Baguette is an intense, extensive work of high jewelry. The entire visible surface of the gold case is covered in gems. The crown grille is topped by the Bugatti Tourbillon's tail light signature, made of 18 baguette-cut rubies. The case was redeveloped to accommodate the technique that's become the Jacob & Co. signature : invisible setting. Unlike a claw or pavé setting, the white gold of the case isn't pushed back onto the gems to hold them in place. Instead, the case disappears under the light of the precious stones.
