    Looks like what was once known as a 'Cocktail Watch'.

    Roskopf is just a specific type of escapement (see image below). 'Roskopf Patent' simply means that it has a (patented) Roskopf escapement inside and says nothing about the maker of the watch. Any chance you can open it and show us an image of the movement? That could help to date this watch. My best guess, at this stage without having seen the movement, would be 1940s.

    Altogether, it looks like the individual work of a jeweler around a standard watch with some done/undone repair jobs = unique piece. So, you won't find an image of a similar one. The crown had been replaced in later times.

    We do not make valuations here (I know, you didn't specifically ask for one) but that one is difficult anyway. An individual watch, highly unusual (if not unpractical) and all a matter of taste. Ladies watches are not much sought after amongst collectors.

    Just a little correction about a common misconception, there is no "Roskopf" escapement ! The pin pallet escapement used in Roskopf watches was invented by Perron in 1798. The Roskopf patent is for a detachable escapement platform.

    A specific, low cost type of a pin pallet escapement might describe it better. But 'Roskopfhemmung' (German original) = 'Roskopf escapement' is a videly used term.

    Hi there,

    just to finish the Roskopf discussion: The feature justifying the patent is the minute wheel sitting friction coupled on the barrel arbor together with the indirectly driven minute hand. This does not only save wheels, i.e. money, but also makes space in the center for a big barrel and/or a big balance. All other features were since long state of the art, and not worth a patent.

    So the Roskopf patent can be combined with every escapement. Here some examples:

    Felsa with Swiss lever escapement (although with separate minute wheel):

    I have to agree with Roland. Roskopf envisaged a particular train layout which allowed use of lever, cylinder and pin pallet escapement. That early on pin palette was the primary use was coincidental.
