Repeating Watches
VerifiedWatches that sound the time acoustically on demand via a slide or pusher, striking hours and subdivisions on gongs, retaining the essential mechanism of pocket repeaters in miniature.
How the mechanism works
The mechanism behind these watches — how it is built, how it developed and its variants — is explained on the Minute repeater page and the related pages below. This page covers what is particular to the watches themselves: identification, terminology and collecting.
Movement & mechanism
- Rack-and-snail mechanism reading the time and determining the number of blows struck
- Miniaturised gongs coiled around the movement, replacing the bells used in larger pocket repeaters
- Activating slide or pusher in the case band charging the striking train independently of the going train
Identification
- A slide in the case band, distinct from the crown
- Visible or audible striking mechanism when activated
- Often combined with other complications (minute repeater chronographs, for example) in the finest examples
Terminology
- Minute repeater — striking hours, quarters and minutes on demand
- Quarter repeater — striking hours and quarters only
Known variations
- Quarter repeater
- Five-minute repeater
- Minute repeater
Pocket-watch ancestry
Repeating mechanisms were invented and refined for pocket watches from the late seventeenth century; wristwatch repeaters required substantial re-engineering to fit the far smaller case, but the acoustic and rack-and-snail principles are unchanged.
Collecting notes
One of the most prestigious and expensive complications to miniaturise successfully for the wrist; acoustic quality and finishing are central to valuation.
