BUT there was no internet then,it would amaze my father if i got this old watch working THANKS
Pictures, Mark! The key to Your questions are good pictures of the watch and the movement.
The only question I can answer: No, from a financial point of view it will not be worth investing into this watch, at least this is very unlikely. This is all about the sentimental value. Honestly, I would only have it cleaned up to make it nice from the outside.
I must say that the watch is a relatively standard sort of watch in its day and age. There are still rather a lot of them about, some in better shape than yours (although a lot in worse) so that supply exceeds demand. As such, it is definitely not worth getting fixed from a purely monetary point of view. However, as a family heirloom, you might consider it. If it is small, too small for a man to realistically wear (what size is it actually?!), it would probably only ever sit in a drawer. The choice is yours.
The watch is Swiss and dates from ca. 1870 to 1890 with some leeway either side. Movements of this sort were made from well before then but the exact bridge layout differed. They were made until just into the 20th century but most watches of that later time were crown wound rather than key wound. An exact identification of the case hallmarks (which is probably silver, by the way) will help date it more accurately. It has a cylindre escapement ("Cylindre") and eight rubies to hold the gearwheels or balance ("huit rubie") and minimise friction to make the watch more accurate and durable. The cheapest cylindre escapement watches had only four rubies and the maximum was 10 so yours is doing all right. The cylindre escapement is inferior to the Swiss lever escapement which is the standard escapement today but it is better than the cheap pin pallet "Roskopf" style escapement.
Good luck in your quest to repair it should you decide to go down that road.
