This special Delma design provides world time in a flash thanks to a dial with 24-hour divisions and a rotating bezel. To use, simply set the name of the city or timezone you’re in on the hour hand and the time everywhere else on earth will correspond to its place on the bezel in relation to the dial. All-steel, water-resistant case, protected crown, quartz movement with date calendar. Steel bracelet or leather strap. (DELMA “Les 24 Heures”)
