Vulcain’s desire to develop the worlds first alarm wristwatch began in the early 1940s. The first prototype was appeared in 1942 but it took another five years to perfect the technology. And perfect it they did! In 1947 the Cricket was introduced as the world’s first wristwatch to have an alarm function. In the years to follow several watch manufactures developed alarm function watches, but none could match the practicality and ease of function found in the Cricket. The key to the success of this watch is the unique movement, caliber 120. This movement has two separate barrels containing springs to store energy. One is for keeping time and the other for the alarm function. By turning the crown counter clockwise the movement barrel is wound, while turning clockwise winds the alarm barrel. This extra barrel means that the alarm will not draw power away from the movement. As a result the alarm can ring, or chirp, for a full 25 seconds. When the alarm goes off you are hearing a hammer strike a membrane and pin that are directly connected to the case back. The sound resonating from the watch is amplified by a second exterior case back with small sound holes similar to those on a violin which allow the sound to escape. The wearer also feels the vibration of the hammer as the alarm sounds, making this the forefather of the vibrate function we currently use on our phones. When the Cricket was shown to the press at the New York Waldorf Astoria it was touted as one of the biggest achievements in watch making. A combination of innovation, public excitement and some fantastic advertisements made it an instant success. This is a genuine slice of horological history, guaranteed to satisfy any watch enthusiasts thirst for something unique and collectible. The 34mm gold filled case is modest by today’s standards, but perfect for those who appreciate the aesthetic of a true vintage timepiece. This watch does not come with original box or papers.
