Frédérique Constant introduces its new Manufacture Tourbillon Grand Feu. With its hand-enameled dial this will certainly become a highly sought-after rarity. Genuine enamel dials are nowadays made by only a handful of manufacturers with an incredibly rich tradition.

Enameling is an ancient technique where finely powdered colored glass is applied to a metal plate. The metal plate with the glass powder is then backed in an oven, hot enough to melt the glass. This enameling process produces a beautiful deep, shiny surface.

Only few of the applied plates will survive the 900+ degree Celsius fire in the oven and produce an even surface. The slightest imperfection in the mixed powder, the supporting metal plate or a dust speckle will ruin the dial and the enameller has to start all over again.

Manufacture Tourbillon Caliber

Based on its award-winning Heart Beat Manufacture Calibre, Frédérique Constant developed its Tourbillon fully in-house with a number of unique features:

• Silicium (or Silicon) Escapement Wheel and lever
• Smart Weight Balancing
• Fast Oscillation at 28’800 BpH
• Tourbillon Cage individually numbered

Silicium (or Silicon) Escapement Wheel

With its three main advantages (Lubricant-free running, Very light (low inertia), Good friction properties) compared to a regular escapement wheel, a Silicium escapement wheel is particularly useful in a Tourbillon mechanism. The reduced weight of the Silicium escapement wheel and the better friction properties result in a substantially higher energy efficiency. As a result, the Frédérique Constant Tourbillon with Silicium escapement wheel has an amplitude of over 300 degrees in dial-up and dial-down positions. Even in the crown-down position, the amplitude is over 275 degrees, which is substantially better than the performance of other high-end tourbillons.
