TWIN TURBO

Name: Twin Turbo
Brand: Jacob & Co.

Rose Gold

Twin Turbo is as desirable, performance-driven and exhilarating as a supercar. It is a Jacob & Co. expression of speed and mechanical beauty in a case and a movement. Its three-dimensional and curvy shape has no equivalent. Its sapphire crystal is one of the most elaborate ever crafted. Like a windshield, it's curved, long, wide and offers an exceptional viewpoint on the inside of the Twin Turbo. The Twin Turbo dial is a piece of smoked sapphire. It reveals the mechanical beauty that lies underneath. It surrounds the most visible and spectacular parts of caliber JCFM01, its pair of triple-axis tourbillons.

From a creative concept to design inspiration. To the first stroke of a pencil through hundreds of iterations. A timepiece like no other comes to life. Part windshield, part body work, part exhilaration, Twin Turbo is designed and engineered like a fast automobile.

After several years of research and development, Jacob & Co. reached the finish line with caliber JCFM04. Its 572 components power a unique set of complications. A flying, triple-axis tourbillon is a rare enough creation. The Twin Turbo has two of them working in unison. The minute repeater function is one of the most prestigious complications in the watchmakers' book. Twin Turbo features a very rare version of it, a decimal minute repeater on Cathedral gongs. Like in several Jacob & Co. movements, such a combination is the only one available today.

TWIN FLYING TRIPLE-AXIS TOURBILLONS

The tourbillons fitted in caliber JCFM04 are held only by their lower end, with no upper bridge. This makes them flying tourbillons. Their carriage is shaped like a sphere, rotating along three axes. This triple-axis structure enhances the benefits of the tourbillon. Using two such tourbillons side by side deepens that effect and augments their accuracy.

GRAPHIC ARCHITECTURE

Jacob & Co.'s unique sense of watchmaking requires that form and function come together. In caliber JCFM01, structure, wheels, levers and bridges are elaborate, symmetrical and use Jacob & Co.'s aesthetic language. The smoked sapphire dial reveals the maze of minute repeater components.

CRANK WINDING

Winding caliber JCFM04 and filling up its 72-hour tank can be a lengthy process. To make it more ergonomic and pleasant, the Twin Turbo’s crown is shaped like a crank, engraved with the word “POWER”.

THE DECIMAL MINUTE REPEATER

Using the slide on the left flank, the Twin Turbo tells time with sound. The minute repeater function is one of the most prestigious ones. Jacob & Co. made it doubly special. Caliber JCFM01 is a decimal minute repeater : instead of chiming quarters of hours, it chimes once for every 10-minute segment. To enhance its sound, Jacob & Co. used another rare feature : Cathedral gongs. The metal rods bent around the movement are almost twice as long as traditional ones. They produce a deeper, longer, more intense sound.

Twin Turbo embraces the hypnotic nature of automobile art. Just like a car can change pace, Twin Turbo shifts gears while retaining its true nature: fast, fun and exclusive.
