The oldest watchmaking complication ? If the world had to wait until 1947 for the first alarm wristwatch worthy of the name, with the advent of Vulcain's Cricket calibre, it was because the challenges related to the striking mechanism had been haunting watchmakers for many centuries. The alarm is probably the oldest horological complication. In fact, it seems that in the 12th century, some monks already had clocks that struck the hours of the services - even before hands had made an appearance. In the 15th century, table clocks often had an alarm mechanism that would strike on a small bell; in 1601, the Corporation des Horlogers de Geneve (Geneva Watchmakers' Corporation) even required that whoever wanted to become a "master" clock and watchmaker make a "small clock with an alarm". In the 16th century, pocket watches with alarms appeared. They had openwork covers to allow the sound to escape. In the 17th century, large "carriage watches" were created. These mechanisms were intended to awaken travellers so they would not miss their connections.
