FrontRunners: How Time Flies

Unlike other perpetual calendar watches, Ulysse Nardin models do not present a problem for long-distance travelers. The company’s GMT perpetual calendar is the only movement of its kind that can be set backward, sparing the wearer who crosses the international date line the ordeal of tweaking a tiny pusher through all the days of the month to get back to the previous day. The $49,800 Ulysse Nardin El Toro (www.ulysse-nardin.ch), which debuted last year, is the most modern incarnation of the GMT perpetual calendar. The travel-friendly watch also has the ability to track a second time zone.
