Ulysse Nardin Marine Torpilleur Dual Time

As business and leisure travel became more commonplace in the 20th century, watchmakers started to design timepieces that could simultaneously display two time zones: local time and home time.

In 1994, Ludwig Oechslin invented the GMT± functions for Ulysse Nardin, offering two push-pieces, “+” and “-”, used to instantly change the time zone of the hour hand, while the “reference time” aperture at 9 o’clock continually displays the home time. Then, in 2014, Ulysse Nardin introduced the UN-334, the first manufacture calibre fitted with the GMT± function, in the Dual Time Manufacture timepiece.

The new Marine Torpilleur Dual Time offers the technical advantages of the UN-334 manufacture calibre and the vintage DNA of the Marine Chronometer (fluted bezel, counter and Roman numeral hour-markers). The movement offers hour, minute and small seconds functions at 6 o’clock, and a large date in a double aperture at 2 o’clock, which can be adjusted in both directions. While the “home time” display operates continually over a 24-hour period in an aperture at 9 o’clock, the small hand can be moved forward or backward very easily to the local time using the “+” and “-” push-pieces at 8 o’clock and 10 o’clock. To top off the refined mechanics, the calendar function syncs automatically no matter the direction of the adjustment.

The Marine Torpilleur Dual Time 44 mm in a polished and satin-finished stainless steel case offers a power reserve of 48 hours, water resistance to 50 meters and a sunray satin-finished blue dial. The timepiece is fitted with a blue alligator-skin strap with a steel folding clasp and is also compatible with a fabric strap with a velcro fastening.
