- Curator's comments
Rather than having a bell, the alarm on this watch employs a small pin which gently taps the users wrist in a fast irregular rhthym, (three taps then two taps, then three taps then two taps and so on).
There is a bracelet watch with similar wrist-prick alarm mechanism in the Musée international d'horlogerie, which can be seen in 'The alarm wristwatch : the history of an undervalued feature' / Michael Philip Horlbeck, 2007, p12, and 'Musée International d'horlogerie, catalogue of selected pieces' / Catherine Cardinal, 2002, p. 230/231.
