Vulcain
Vulcain's history began in 1858, in the watchmaking workshop set up by the Ditisheim brothers. Vulcain rapidly rose to prominence for complication timepieces that won medals at several World Fairs. It owes its international renown to an innovation launched in 1947: a mechanical alarm-watch. Its popularity with American presidents since Harry S. Truman has earned it the nickname of "the President's watch".
