Ulysee Nardin Anchor Blue Enamel Tourbillon
The Ulysse Anchor Tourbillon was eight years in the making and a world first. Housed in a 60-second tourbillon cage, the watch’s architecture is based on the principle of flexible mechanisms, exploiting the elasticity of flat springs. It presents a constant force escapement made entirely of silicium, and features a circular frame with a pallet fork that moves without friction. The pallet fork is fixed in the center and supported in space on two minuscule blade springs. Mounted perpendicular to each other, they are subjected to a bending force that curves and keeps them in a bi-stable state. The result is a positive energy balance that maintains the oscillations of the balance wheel at a constant rate without motor torque influence. Functions are: hours and minutes, power reserve indicator and tourbillon.
The case, in 18kt white or rose gold, measures 44mm. It has double AR-coated sapphire crystals and it is water resistant to 30 meters.
The dial is translucent blue enamel with gold hands. Handcrafted in-house at Donzé Cadrans, a member of the Ulysse Nardin group of companies, the enameling technique is specialized and intricate. Cavities, or cells, are formed in a thick metal surface then filled with moist, powdered, blue enamel and fired until it melts. After cooling, it is sanded by hand to expose its azure radiance.
It comes on a blue alligator leather strap with matching gold buckle.
