CFB T3000 MANUFACTURE MOVEMENT
Floating Tourbillon
Unlike traditional tourbillon features, it is neither mounted on the movement’s main plate nor in an overlying bridge. Tourbillon with a peripherally mounted rotating carriage. With the tourbillon of Carl F. Bucherer, the mounting of the carriage is ensured by three ceramic ball bearings, which support and guide the bearing wheel at its circumference.
These can be adjusted by an eccentric mechanism to set the clearance optimally. In comparison to conventional tourbillons, this construction allows for a lower height and an unhindered view of the rotating carriage from both sides.
COSC-certified chronometer
The CFB T3000 manufacture caliber, comprising 189 individual parts, stands out because of its exceptional accuracy and first-class precision, making it one of the few currently manufactured tourbillon movements to officially be chronometer certified.
Silicon escapement
The escapement, i.e. the pallet and escape wheel, is made from silicon. Due to its lower inertia, it requires less energy to move, helping increase the power reserve to at least 65 hours, while enhancing the magnetic resistance of the watch.
Stop-seconds function
A further distinctive feature is the stop-seconds function, which allows for the rotation of the tourbillon cage to be stopped. This means the watch can be synchronized with a standard time and thus set to the second.
Technology Meets Aesthetics
The engineers of Carl F. Bucherer decided to position the tourbillon at 12 o’clock, where it is visible through an opening in the dial. This window is encircled by a 60-seconds scale and allows the tourbillon to also serve as a small-second indication. A second hand is positioned on the tourbillon cage, which rotates around its own axis once every minute.
PIONEERING PERIPHERAL TECHNOLOGY
What is peripheral technology? It means that parts are not mounted centrally on their axes but rotate around their own peripheries on ceramic ball bearings. This allows for thinner watches and an unobstructed view of the corresponding elements, a feature that is very attractive to watch enthusiasts and aficionados.
THE PERIPHERAL ROTOR
Bidirectional peripheral automatic winding system
Automatic winding mechanism with peripherally suspended rotor ring that is mounted with three ceramic ball bearings on its inner circumference. The three ball bearings are mounted on springs and act as a shock absorber. In contrast to centrally mounted rotors, the peripheral rotor ensures an unhindered view of the movement and allows for the watch’s flat design.
