The present watch is a fine and very well preserved example of a "Mystérieuse" watch. It is furthermore believed to be one of only around 10 known to date with gold cases as opposed to the more commonly found silver version.
Patented by Armand Schwob & Frère in Paris on 24 January 1889, the "mystérieuse" or "mystery" watches were built on the principle invented by Robert-Houdin for clocks: the watch appears to work without any mechanical movement, the hands without any apparent means of connection. In fact it is driven by the crescent-shaped movement concealed above the dial in the border, the hands attached to and revolving along with the glass plates.
Probably intended for the Chinese market, several watches of this model are known with the additional signature of the retailer J. Ullmann of Hong Kong and Shanghai.
