I read the following on http://timeuhren.free.fr/breguetfr.htm :
1926 : Brevet de la montre sans aiguille ? cadran tournant et heures sautantes dans un guichet
and was wondering wether anyone had a picture of any producted watch of this kind.
I am also wondering wether anyone could tell me more about it and its eventual relation with Vincent Calabrese's baladin watch.
Any help would be appreciated.
have a nice day
