Ulysse Nardin Dual Time ref. 243-55, complete set

The Ulysse Nardin Dual Time reference 243-55 channels the manufacture’s extensive maritime heritage into a highly practical companion designed for frequent travelers. In 1993, Ulysse Nardin pioneered the GMT± complication (patent CH 685 965) with its signature plus and minus pushers integrated into the case flanks, allowing the wearer to instantly jump the hour hand forward or backward one hour at a time. This ingenious mechanism enables effortless time zone adjustments without interrupting the movement's normal timekeeping or requiring the watch to be removed from the wrist. Complementing this function is a digital "home time" display window at 9 o'clock, which allows the traveler to keep a constant reference to the time of any person, office, or location they need to stay connected with. Two years later in 1995, Ulysse Nardin introduced another breakthrough with the addition of their “big date” double window display (patent CH 688 671) that uses two discs to create an enlarged, highly legible date display at 2 o'clock. Together, these two apertures sit asymmetrically within a finely designed dial defined by a radial sunburst pattern emanating from the sub-seconds at 6 o'clock. Geometric details, such as the dodecagon-shaped outer track and sharply faceted indices, lend the dial a distinctly architectural character. The watch maintains a modern profile in a thoughtfully proportioned 42mm stainless steel case with 100 meters of water resistance, befitting Ulysse Nardin's heritage as a manufacturer of marine chronometers.
