Ulysse Nardin drops a new marker buoy on the capricious ocean of fine watchmaking introducing a world first, the Ulysse Anchor Tourbillon, the quintessence of avant-garde mechanical technology.
The outcome of eight years of research and development, the constant Ulysse Anchor escapement, made entirely of silicium, displays hitherto unknown architecture based on the principle of flexible mechanisms exploiting the elasticity of flat springs.
The culmination of the development work on the prototype version presented in 2014, represents the height of timekeeping sophistication today: 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 peak of traditional expertise.
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. This caliber UN-178 is housed in a rose gold or white gold case enhanced with a white Grand Feu enamel dial. Available in limited edition.
