Cutting Edge Technology

Ulysse Nardin is one brand that continues unabated in its quest for innovation by introducing cutting edge technology and mechanisms in its timepieces. Decked out in a nautical-inspired design is a novel marine chronometer which displays on its dial, hand-crafted wood marquetry evoking a ship’s deck. 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 complex. 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.

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 Tour-billon model, a watch worthy of the high seas.

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 0.0357 mm 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 turn-buckle. 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.

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.

This compact timepiece of mechanical ingenuity is housed in a white-gold case measuring 44 mm in diameter and is 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. Hand-crafted 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 and available in a limited edition of 18 pieces on an alligator strap with a white-gold folding buckle.
