A pioneer by nature, Zenith filed a first patent in 1913 for a sophisticated watch on which the alarm time could be set using a special bolt device. This first milestone paved the way for the pocket-watches launched in 1915 and available in several versions, meaning with a gold, silver, blackened steel or white metal case. These pocket-watches have proven themselves highly functional, since in addition to the alarm function, the case features a hinged cover at noon which, once deployed, serves as a base or carrier for the watch and therefore makes the musical chiming of the alarm more clearly audible. The latter is made by a hammer striking the gong which is independent from the case middle. With this model, Zenith offers a perfect alarm watch that is neither thicker nor bulkier than a classic pocket-watch. The double-function crown cleverly winds the movement in the usual left to right direction. In the other direction, it supplies the striking mechanism power reserve. The case middle is fitted with adjustment pushers framing the crown. The righthand pusher serves to adjust the time and the left-hand one to adjust the alarm time ?? which is read off on a subsidiary dial at 12 o’clock. This dial version features luminescent Arabic numerals. The sweep seconds hand is classically positioned at 6 o’clock as on most pocket-watches, so that the dial remains uncluttered and the user is never disturbed in reading the time. The design of this alarm watch is intended to be understated and authentic, thus ensuring it is ready for any type of use its wearer may require, wherever he may find himself and in any kind of situation.”
