Welcome aboard! Cutting edge technology and innovative mechanisms are all aboard this high-precision craft decked out in a
nautical-inspired design. On the dial, handcrafted wood marquetry evokes a
ship’s deck, while the time display is original and creative: a boom pulled by
super-strong nanowires indicates the minutes, while the hours are displayed on
two concentric disks. The patented device, which is regulated by a second
barrel, also incorporates a majestic tourbillon. Undeniably exclusive, this
timepiece from the Marine Chronometer collection is produced in 18 white gold
pieces.
Ulysse Nardin is in its element when venturing on the high
seas, as evidenced by this latest creation. In the innovative Grand Deck Marine
Tourbillon model, the retrograde minutes display takes the form of a boom.
The
technology is visually fascinating, and as complex as it is accomplished.
Linked to a 60-second flying tourbillon, this patented system is drawn by a
super-strong hi-tech fiber that is thinner than a human hair. Impressive all
round, the timepiece showcases breakthrough technology in the unmistakable
nautical-themed design of the Marine Chronometer family, of which it displays
the legendary traits. The manufacture, as a pioneer in marine chronometers, has
a long and distinguished history of producing high-precision seafaring
instruments that have helped conquer the oceans since the 19th century. This
collection reinvents these tried-and-tested attributes for the modern era.
Centuries of expertise and a tireless spirit of innovation have produced the
Grand Deck Marine Tourbillon model, a watch worthy of the high seas.
Full Sails
In a proud nod to its maritime roots, the Grand Deck Marine
Tourbillon model incorporates the elements of a ship’s deck to display the time
in a creative and original manner. The minutes hand is replaced by a boom – the
horizontal spar used to angle the head sail. Working like the halyard cord that
is used to hoist the sails of a ship, a wire pulls the boom across a graduated
arc. The boom jumps back once an hour, its speed regulated by a
purpose-designed retrograde mechanism. The mesmerizing leap takes 3 to 4
seconds and can be viewed through the case back.
The boom is pulled by a
nanowire that measures a mere 0.0357mm in diameter and is capable of
withstanding traction of 1.41 kg without stretching. The nanowire is made of
polyethylene Dyneema® fiber, a material that is used in ship’s rigging and is
many times stronger than steel. In a first for watchmaking, the transmission
system loops the wires through a rigging screw: two strands are visible, and a
third strand fastens the turnbuckle. The patented system, which is visible on
the dial, is exclusive to Ulysse Nardin. Working like the winches that hoist
the sails on deck, four ‘pulleys’ use a drive gear, a spiral tensioning spring
and two lock pins. The jumping hour is driven by two large concentric disks
that turn in real time, and is displayed through a double aperture. A corrector
positioned at 2 o’clock can be used to set the time quickly.

Wind In Its Sails
The manufacture’s Caliber UN-630, a 60-second flying
tourbillon with manual-winding movement, contains 469 components and oscillates
at a frequency of 3 Hz. Despite the considerable power requirements of the boom
display, the movement offers optimal precision and a generous power reserve of
over 48 hours. A first barrel is devoted to the time-telling mechanism; a
second barrel supplies power to the complication, i.e. to the display of hours
and minutes. The latter device is regulated by a specific escapement that
collects information from the time-telling mechanism. The double-barrel design
(one for the movement and another for the display) prevents the complication
from interfering with the workings of the watch. To the rear of the movement,
the leading and unloading of the balance spring can be viewed through the
skeletonized barrels, a feature that is both functional and fascinating. When
the watch is wound, the spring winds up into the center of the barrel.
Conversely, when the spring is spent it unwinds out towards the edge of the
barrel.
All Aboard!
This compact example of mechanical ingenuity is housed in a
white-gold case measuring 44 mm in diameter and water-resistant to 100 meters.
The dial of the Grand Deck Marine Tourbillon conjures a ship’s aesthetic and technical
finesse. The fluted bezel is complimented by a screw-down crown with blue
rubber molding. Handcrafted marquetry evokes the sun-soaked teak of a ship's
bridge. The blued-aluminum boom sweeps across a translucent arc of blue spinel
that extends from 3 o’clock to 9 o’clock. The boom is drawn by a wire connected
to four pulleys secured with blued star-shaped screws, which are echoed by the
tourbillon decorated with the Ulysse Nardin anchor. In a final flourish, border
detailing and ornamental wires that adorn the top of the dial offer further subtle
references to nautical design. In the signature of the Marine Chronometer
collection, the Ulysse Nardin logo, placed between two floating maritime
symbols that correspond to the letters U and N, echoes the design of the ship’s
chronometers that were historically produced by the manufacture.
This timepiece is exclusive by nature, available in a
limited edition of 18 pieces on an alligator strap with a white-gold folding
buckle.
