    Help!

    Hi!
    I need help with this pocket watch that belonged to a great grand father. I want to know the name of the watchmaker, the age of the watch and any other information I can get on it! Will really appreciate any help as I am in India and its really difficult to get good professional help on such watches here.. Some info on it- the dial says- "inflexible lever" and "swiss made" on it. The inside of the watch has 3 readable engravings- "Advance/retard", "swiss made" and "+35344". I am guessing the +35344 is the swiss patent number. I did try to search the net on this number but could not get any results. Photos are attached..
    Help!!

    It will be hard to get all that you want, but if it is of any help, that could be Pierce cal. 16 movement in your watch, or one of it`s variations.

    Hi -

    First of all, welcome to the forum and WUS! Hope we can help you...

    I went through my Shugart #29 and there is no Swiss-made movement that matches that particular caliber: the additional part of the balance wheel bridge is unusual, to say the least.

    I'm going to venture a guess, though: a post-WW2 pocket watch. The reason?

    Design of the movement. Whilst going through the Swiss pocket watch movements, I saw that most of them were either 3/4 plate movements or what are called "finger" movements, where there isn't much of a plate at all and all pivots are held by metal fingers instead. Only the later pocket watch movements - and the fakes, of course - were different.

    Sorry not to be able to help too much: there are many, many watches out there that simply cannot be readily and easily identified, given the lack of company history and general disinterest...sad, but true.

    Re: Help!

    Dear JohnF,
    I think I disagree with you.
    The most unusual balance bridge design is very nice.
    When I see the case design.
    Better pictures would be nice thouhg!
    I see more something between 1910 till 1930
    the very round crown for example, is not post WWII.
    The details in the case under the crown is not post WWII.
    most motivation for me is: unusual pocket watch desings after WWII are unlikely, they are just commen standerdised movements, as it was a dying watch, so why use something special?
    So I think it is WWI eara, or interbellum.
    Q1: what does the dial exactly say? I can't read it... edit: sorry, you said it already!
    Q2: is the glass flat?
    Q3: what is the height of the case, how thick is it?
    Q4: is there a double case back?

    nice day,
    RJ van Melle.

    PS: did some investigation: I will soon come with more details: this perticular watch might be VERY interesting as it points out a certain development in the lever escappement development, from English lever to Swiss lever, did find some references to inflexible levers, all dated back to the end of the 19th century. When I know more I let you know. but really identifyng will be difficult......

    Leon Levy & Freres

    A patent number search of CH35344 on the European Patent Database shows that Leon Levy & Freres owned the patent.

    Leon Levy & Freres later became Pierce SA.

    Now that is interesting.... looking at the drawings in the original
    patent document, then this looks like a shock protection system
    to protect the balance pivots. I wish I could read the description but
    it's in French.

    I hope someone with better french skill comes along, but from what I can discern, it's not for shock protection; it looks like it's designed to allow the balance wheel to be precisely positioned to maximize the interaction with the lever. Its a bit too technical for my language skills though.

    I believe that rmelle speaks French.

    I think another source of information about the "Inflexible Lever" is Chamberlain's "It's About Time" which is a truly exhaustive source of information for everything concerned with the lever escapement up until about 1950. The name is very reminiscent of many English attempts to improve the function of the lever itself.
