Ulysse Nardin Grand Deck Marine Tourbillon. The hand-crafted wood marquetry dial evoking a ship's deck houses a truly creative time display with the retrograde minutes display taking the form of a boom, the horizontal spar used to angle the head sail. Linked to a 60-second flying tourbillon positioned at 6 o'clock, this patented system is drawn by a super-strong (many times stronger than steel) hi-tech fiber that is thinner than a human hair. This nanowire measures a mere 0.0357 mm in diameter and is capable of withstanding traction of 1.41 kg without stretching - best replica Ulysse Nardin watches.
Working like the halyard cord that is used to hoist the sails of a ship, a wire pulls the blued-aluminum boom across a translucent graduated arc. The boom jumps back once an hour, its speed regulated by a purpose-designed retrograde mechanism. The leap takes 3 to 4 seconds and can be viewed also through the case back.
Calibre UN-630, a 60-second flying tourbillon with manual-winding movement, contains 469 components and oscillates at a frequency of 3 Hz (21,600 vph). Despite the considerable power requirements of the boom display, the movement offers a remarkable power reserve of over 48 hours. A first barrel is devoted to movement while a second barrel supplies power to the complicated display system of hours and minutes https://www.captainthewatch.is.
