Full Alert: A History of Alarm Watches

Postby koimaster » April 26th 2018, 8:34am

The alarm was the most useful complication ever to be fit inside a mechanical watch.

The practicality of a tourbillon is debatable and apart from an indulgence for mindless fidgeting, a chronograph rarely sees use but despite this, the mechanical alarm is no more. What once involved springs, hammers and membranes is now a soulless electronic beep controlled via a tap on a screen.

There are individual alarm pocket watches dating back to the 17th Century and water clocks going back even further but it wasn't until 1899 when the Durrstein brothers patented the first mass-produced movement with an alarm complication. The large size of a pocket watch caliber allowed the brothers the freedom to use an extra large main spring that could power both the timekeeping of the watch and the alarm complication, which at full charge could chime for thirty seconds.
