    Default J. Boss Pocket Watch Case

    Could anyone tell me if J. Boss ever made a solid 14K gold pocket watch case? I have a J.Boss case marked 14K but it has the Keystone stamp with the Co. in the middle. The back is also stamped with the Keystone stamp. thanks...

    EKCreations,

    Welcome the NAWCC American Pocket Watch message board.

    James Boss patented the "gold filled" watch case in 1859. Anytime you see a JBoss marked watch case it will be "gold filled" and not 14k solid gold.

    The Keystone-Watch-Case Co. purchased the patent and trademark rights for the JBoss case from the previous owners and used it with their own trademark.

    The "Crown" added to the JBoss trademark indicate a "25 Years" warranty. The trademark without the "Crown" will be 10K "gold filled" and will have a 20 year warranty.

    After Jan. 1, 1924 a "guaranteed" marked case was prohibited by the U.S. Govt. They were only mark 10 or 14 "gold filled" after that date.

    I might add that some of the early J Boss cases were purposely marked in ways that were meant to fool buyers.

    As you can see by what others have posted that these cases were meant to trick a naive buyer.

    I have a question about my 1915 J Boss Case
    I might off missed it in the FAQ section, but I didn't see an entry for
    this case(maybe I missed it).
    My question is what karat gold did they use in these cases.
    I would assume if it doesn't say 14k than it must be 10k or less?

    edit sorry i don't see my photos will try again
    Thanks

    One can't be sure if the case isn't marked.

    Some people believe that if it is a 25 year case than it uses 14K gold and that it is a 20 year case its 10K gold. They may be correct, but I personally would not make a monetary decision based upon that rule-of-thumb.

    I suppose that there may be some non-invasive testing that can be done, but I've never used any method of testing.

    My earliest J Boss case is on an 1864 AT&Co grade movement. It has the original
    J boss patent stamp. One should recognize the Tucker regulator was added sometime
    in the mid 1870's for better time regulation on this Civil war era movement.

    SN#98514 on movement.
