In 1947, Vulcain invented the first wristwatch equipped with a genuinely operational alarm function. This innovation was to earn the brand its reputation with American presidents from Harry S. Truman onwards.

1914: The first serially produced wrist alarm clock is introduced
μαλλον καλα διαβασες , Although credit for the birth of the modern day wrist alarm goes to Eterna, it wasn’t until the Vulcain Cricket line in the 1940’s that the function would gain in popularity. Earlier offerings were either too complicated, inaccurate or just not loud enough. Vulcain was able to overcome these shortcomings to produce more desirable alarm watches. This lead to Jaeger-LeCoultre getting in on the game in the late 1940’s and progressing the style with the development of the Memovox, the first automatic watch with an alarm.
