    I was recently gifted a silver metal full hunter pocket watch.

    The front case is stamped with "Roskopf patent swiss made". The back has a design and the words "Medaille D'or Geneve 1896"

    The inside of front case is stamped 93486 and the back 493486.

    I would love some more information on the history of this watch and if anyone knows the age?

    Thanks.

    Welcome to the board, GWS :)

    "Medaille d'Or Geneve 1896" indicates that the maker of the watch won a gold medal at the Geneva Exposition of 1896 ... whether for this particular watch or others. That dates the watch to 1896 or later, and my guess is that they would not have continued to use that Gold Medal for marketing purposes for longer than 10 years.

    The Roskopf escapement was patented in the 1860s and was widely used for lower grade watches.

    The two numbers on the case are effectivley the same; often the first one or two digits of the full number were omitted where space was limited.

    I don't think we can tell you much more without photos of the watch - especially the movement and any case markings.

    This is an interesting one:Frederick Rosskopf developed his watches to meet the growing demand of the working classes in the second half of the 19th cent. for a reliable and affordable watch.He simplified the watch technik of his time,chose (relative)cheap materials and the result was much better than expected.The Rosskopf soon gained a good reputation,and licences were given to other producers to make their watches according to the Rosskopf desing.The main technical features of Rosskopfs are:The motion work being driven directly by the barrel and the Rosskopf pin pallet escapement mounted on an adjustable part of the front plate together with a low jewel count.The watch above shoes the typical Rosskopf train,but I see anchor and ew-pivots jeweled,and what I can see of the ew doesn´t look like a pin pallet.So I think this to be a later and improved example,maybe by Ferdinand Bachschmid-a former employee of Rosskopf-who is known for his improvements of Rosskopf calibres or Brand und Hoffmann and others.The actual quarterly journal of the DGC contains an article about improved Rosskopfs and their makers.Please more pics without the crystal over the mvmt. and see that You find additional signatures/logos on the plates inside,on bridges,barrel covers and even on anchors.

    I need to read some more, lots of the technical stuff you are saying means nothing too me yet. Will try and remove the glass but not sure how to go about it.

    Oooops .... no I don't think you should try to remove the glass movement cover - that is a specialist job which you would need an experienced watch repairer to perform!

    Instead of trying that, I would suggest you take a further picture of the movement, but this time with good fixed lighting rather than a flash and make sure you avoid reflection. It's not easy, but you'll soon get the hang of it with a little experimentation - your other photos are excellent :thumb:

    one of the rare and original Roskopf. a true "Georges Frederic Roskopf " made by Wille Freres
    sometimes there is a WE(Wille) on the lever escapement

    "Following Roskopf’s death in 1889, a number of firms claimed to be his “true successor.” But Wille Freres alone actually had the rights to the Roskopf label. They had been using the Roskopf trade mark for years—with his consent—before G. F. Roskopfs death."
