|Model||Ulysse Nardin Grand Deck Marine Tourbillon|
|Size||Case Diameter: 44 mm|
Designed to look just like the teak deck of a beautiful sailboat, the time display of the 45 mm watch pulls a boom across the wooden marquetry dial using high-tech nanowire around a series of winches that emulate the rigging of a ship. The boom-style retrograde minute hand moves along a translucent blue arc minute counter and offers the coolest animation when it hits 60 and returns to zero. Hours are indicated via a double-disc “big” jumping hour display. Because setting the time using this system can be slow, Ulysse Nardin designed the in-house made calibre UN-630 movement with a quick-set system for the hour indicator. A pusher above the crown allows you to advance the current hour in one-hour increments. In addition to the jumping hour indicator and the retrograde minute hand, the UN-630 movement also has a 60-minute flying tourbillon. Look out for the high-end sailing boat-style pulleys that move the small wires which are just 0.0357mm in thickness. The Ulysse Nardin calibre UN- 630 movement is manually wound and produced from 469 parts operating at 3Hz with a 48- hour power reserve. The movement has a unique finishing, as seen through the rear of the sapphire crystal caseback window, and doesn’t look like any other Ulysse Nardin watches that come to mind. Two barrels are used in the movement, with one to power the time regulation system and another for the complications.
