Two of the most iconic alarm watches Vulcain Cricket and Jaeger-LeCoultre Memovox

An alarm watch is designed to ring a signal at a defined time. Everyone probably has cursed their alarm once, but few people can deny their usefulness. It is probably one of the oldest horological complications. The first alarm clocks were stationary. With the development of exchange and travels, these mechanisms were included into pocket watches, as of the 16th century http://www.tarawatch.co/.

The first alarm wristwatch was patented in 1908 by Eterna, but success really spread after the creation in 1947 of the legendary Vulcain Cricket calibre, which truly raised the bar for such watches. Among the other undeniable references is Jaeger-Lecoultre, with the Memovox, the first automatic alarm watch, released in the early 1950s. The two brands also produced dive watches (respectively the Nautical and the Polaris) featuring mechanisms audible underwater, to help monitor the ascent back to the surface.

Traditional mechanical alarm watches ring by means of a mainspring, tensioned to power a hammer striking on resounding parts: a bell, a gong or the case of the watch itself. The alarm mechanism is coupled to the movement, with a wheel commanding a cam to trigger the signal, at the desired time. Cheap luxury brands fake watches,aaa Quality,Fastshipping all over The World.
