Anyone know when Jurgenson (en?)-style movements were first popular?

    I just bought another movement with the half-circle Jurgenson-style bar surrounding the balance wheel. Does anyone here know when that was first patented, or when the last one was produced in Switzerland? Thanks.

    I don't know but I have a Key wind Key set watch of this type from them from the 1840's. This watch was possible made by Louis Audemars and is typical of their style whether they made it or not.

    It would not have been patented. One of the recommendations made to the Swiss industry after the US 1876 exposition was that the Swiss start a patent system suggesting there was no sucj system during teh 1840's and earlier.

    I also associate the bar around the balance wheel with Locle made watches. It seems to have developed as a regional style and my guess is that it arose around 1840

    I would have thought it later than 1840 though, many aesthetically pleasing movements were patented in the late 1850's and early '60's, so there must already have been a patenting system by 1876.

    There was patenting but not in Switzerland. Jurgensen had a major share their business in teh US and A US patent woudl have protected the firm there but not in Switzerland and this style of movement is too common to have had any protection.

    Most Swiss movement are difficult to date precisely. Serial numners are not sequential and many records are gone and they did not date letter hallmarks, bur Jurgensen records still do exist and my example is date to teh 1840's by these records.

    Here is what it looks like

    I think I have posted this before and I apologize for the repitition.

    The original question was when it became popular. This is not a measurable term but this style, as this example shows, was at least in use by the mid 1840's.

    Well, at least one thing should be clear- I've never seen this design in a fusee, only cylinders and levers. That in itself says something, anyway. Thanks!
