The Twin Turbo Furious Sapphire Crystal timepiece features both a fully transparent sapphire crystal case and a decimal minute repeater, a first in the world of haute horlogerie. The case took approximately 15 months to design and produce, combining the latest in high-tech design and manufacturing with traditional hand polishing.
The case provides a full view of the complex machinery of the Twin Turbo Furious, powered by the manual winding JCFM05 movement with a 50-hour power reserve. This includes the groundbreaking group of exclusive complications, such as the decimal minute-repeater, twin high-speed tourbillons, mono-pusher chronograph, and a pit-board style reference indicator.
The Twin Turbo Furious combines the exhilarating energy experienced in the world's fastest automobiles with the unparalleled refinement and mechanical complexity only present in the universe of haute horlogerie. Powering the Twin Turbo Furious' main time display and monopusher chronograph functionalities are its twin triple-axis tourbillons, spinning in a succession of lightning fast, calculated movements, the Twin Turbo Furious can depend on two regulating organs. Each of these triple-axis tourbillons are composed of a total of 104 components - and yet weigh only 1.15 grams.
Part of the Twin Turbo's 832-component JCFM05 Manufacture Jacob & Co caliber is a decimal minute repeater - the most exotic and rare among chiming complications. Pull the sapphire crystal level set into the left-hand side of the sapphire crystal case to hear the crystal clear sound of its cathedral gongs.
The Twin Turbo Furious Sapphire Crystal is yet another groundbreaking Jacob & Co creation, one that is like no other to have ever existed in fine watchmaking before.
