Orologio del Viaggiatore con Bussola-Meccanica damascata - 1850-1900

Traveler's Watch, with compass predisposition (I say predisposition because the anti-magnetic needle isn’t present, I hope you can forgive me but I don’t have time to look for it) and Skeletonized Mechanism
Note that I have a doubt about the absence of the back metal cover door; the watch indeed has a glass instead of the back cover, and my doubt is that it could have been customized, making it skeletonized at a later time. But it is also true, and I think it’s a reasonable line of thinking, that since this watch also has a use that favors orientation with the presence of the Compass, it could have been conceived and born that way (moreover the mechanism is aesthetically very beautiful and displayed; it greatly increases impact and the Wow factor).
Regarding operation, the watch works, but in this case I feel compelled to recommend a cleaning and lubrication, as, always choosing the path of correctness, it seems right to point out that the watch runs for several minutes, but when turning it from the skeleton side to the dial side it sometimes tends to stop. This is surely a problem due to the extended period of inactivity of the watch, for which lubrication might be enough, at most a cleaning.
The key present is ancient and contemporaneous in age, but I don’t think it is contemporaneous with the watch because it can wind the watch but the inlet is a bit stiff and therefore could be a narrower size (the key present is unlabeled; I tested with a universal key and that specific one is number 7).
Stunning watch truly.
The front dial shows a threading on the lower part but no burr.
