We previously showed you the Ulysee Nardin FreakLab, which utilised new silicium components. Another release for Baselworld 2015 from Ulyse Nardin that utilises silicium. Introducing the Ulysse Nardin Anchor Tourbillon.
The Ulysse Anchor escapement made entirely of silicium is the result of eight years of research and development. The prototype version was presented in 2014 and after further developments, it is ready in 2015. This was done in In collaboration with Sigatec, a co-owned company specializing in the production of silicium micro-components
First, no longer constrained by a pivoting staff, the pallet fork moves entirely without friction; second, the geometrical improvements made to the pallet fork, the escape wheel and the flat springs have resulted in a constant-force escapement; and to crown all of this, this new coinage in watchmaking is brought aboard in a tourbillon cage.
The new constant Ulysse Anchor escapement features a circular frame with a pallet fork fixed in the center, supported in space on two blade springs less than a tenth of the thickness of a hair in diameter. Mounted perpendicular to each other, these are subjected to a bending force that curves them and maintains them in a bi-stable state.

The new Ulysse Nardin Anchor Tourbillon featuring the brand new Ulysee Anchor Escapement in Rose Gold
This astonishing construction is housed in a 60-seconds tourbillon, whose cage comprises 35 components but weighs no more than 0.4 grams. With its constant amplitude, irrespective of how much the two series-mounted spring barrels are wound, this exceptional oscillating mechanism is a major step forward in the field of chronometric accuracy. Visible through a large opening in the dial at 6 o’clock, it is encircled by the indication of its power reserve of at least 7 days on a 140° arc.
The caliber UN-178 is housed in a rose gold or white gold case 44mm in diameter, in the Classico collection. A setting with traditional lines enhanced with a white Grand Feu enamel dial created by the unrivaled expertise of Donzé Cadrans, a dial-making specialist company owned by Ulysse Nardin.
Available in two limited editions of 18 pieces each, the Ulysse Anchor Tourbillon will be in the retailers’ display windows from May.
