    watch ID #3 - Hard to find maker, mechanism

    Finally, I can't find this maker or any reference to "parachute compensating curve" either. Some number markings on back, as well as an "FJ" and a tiny impression that looks like it says "Argent" with a small shield. 1.93" across.

    A middle 19th century ... I would have thought it Swiss and not English... I don't recognize the hallmarks. But 'argent' is French for sliver, if I remember my 8th grade French correctly... It was once a grand movement but rust seems to have attacked it. Restoration will be expensive.

    "The watch has to be surrounded by a history.
    You need more than just a great design. You need to create an atmosphere around the product.
    Who is the company behind it? Why are they using this material?
    People need to be able to identify the watch with themselves. It's based on emotion." - Ralph Furter

    ...that's just my opinion and I've been wrong before and will be again and might be now!

    You have got a very interesting movement here.

    The 'parachute' is the earliest form of shock protection (invented by Breguet). This is essentially a spring mounting for the balance staff jewels. If you notice, the jewel mounting is at the end of a circular spring.

    The 'compensation curb' is an early form of temperature compensation. Here, the curb pins are mounted at the end of a curved piece of metal (this is visible over the balance spring). Changes in ambient temperature, therefore, change the effective length of the balance-spring.

    Hope this helps.

    Kind regards

    Definitely Swiss. Dates probably from 1840-1870. John L Williams was probably a London watch merchant or jeweler.
