While integrating the annual calendar complication into a nautical chronograph, Ulysse Nardin’s main goal was to combine elegance with an easy-to-use solution.

The new Ulysse Nardin Nautical Chronograph Annual Calendar is actually very simple to use.

Between a perpetual calendar that requires no corrections before 2100 and a simple calendar that requires five manual adjustments a year, the annual calendar recognizes months of 30 and 31 days, with the exception of February. So it only needs to be corrected manually once a year.

Simplicity begins with the UN-153 movement. Ulysse Nardin’s watchmakers succeeded in reducing the annual calendar mechanism to a dozen add-ons, which on average required at least thirty elements. This movement requires only three additional wheels. The movement allows the time and date hands to move in either direction.

Made entirely in-house, including a silicon hairspring, this self-winding movement beats at a frequency of 4 Hz (28,800 vibrations/hour) and has a power reserve of approximately 52 hours. Shopping replica watches

In addition to the central hands indicating the hours, minutes and seconds, the dial – available in white or blue – features a 30-minute counter at 3 o’clock, a 12-hour counter at 6 o’clock and a continuous seconds counter at 6 o’clock 9:00. The latter also features a month display, thanks to a red hand that indicates the current month. Finally, the date is displayed in a circular aperture at 6 o’clock.

The design of the 43mm stainless steel case features elements typical of the Marine collection, including a ribbed bezel and a rubber-covered screw crown to ensure water resistance to 100 meters/330 feet.

The Ulysse Nardin Marine Chronograph Year Calendar is available with a folding clasp strap (rubber or alligator leather) or a steel bracelet.
