The information you have provided shows that it is an eight jewel ("huit rubis") cylindre escapement ("cylindre") pin set (pin next to the winding stem in the photos) watch from the late 19th century. As such, it is not terrribly special - cylindre escapement watches were fairly run of the mill at that time (but still better than zero jewel pin lever "Roskopf" watches). The main value of your watch would be the gold content. That does not mean that you should have it melted down! - if it still runs, it should give you decent service and perhaps make a nice heirloom.
...but you would need to have a look at the other side of the movement to confirm or reject that hypothesis. The adjustment lever on the balance is bent over rather a lot, showing that the watch could do with a good service. If you are not willing to spend the cash on that, I would advise you not to wind it regularly since it may damage the watch.
