Nice and rare antique pocket watch with double hours time scale, changing on demand.
There is enamel dial under the metal ones. Normally the black roman numbers I - XII are visible in the windows of the dial.
When the top button is pressed, the numbers are changing to the red roman ones from 13 to 24.
Unusual complication. The watch is French production, not a Swiss and is patent prohibited, there is "Brevete" inscription on dial.
Same watch is shown in Reinhard Meis book of pocket watches by number 721.
The watch is in nice technical and cosmetic condition.
Gunmetal case is in descent condition with some discoloration.
Mineral glass, spade hands. Please look photos.
