This is an antique 19. It is open face, and measures 50mm in diameter. The case is 18K gold. The inner lid looks like gilt metal, and is marked with French writing, including CYLINDRE EN PIERRE with translated to STONE CYLINDER.
The case is excellent, with no dents or damage. The case back has very elegant designs on it, and is not worn. The watch runs strong, but I have not checked it as a timekeeper. The pump repeat is a ¼ repeater. It also works, but the gongs are dull sounding, and not light.
Looks like the gongs are touching either the movement or each other, so you may want to get them fixed/adjusted. The porcelain dial is excellent and original to the watch.The gilt hands do not match. Looks to me like the minute hand has been replaced. The watch has a bulls-eye glass crystal. This is a very nice looking watch, and a stone cylinder is rather rare to find.
