    Some of my internal letterd from the ball family indicated that they swapped out escapements sometimes as many as three or four times on watches when trying different variations. I came across this ball watch today. Check it out. Thoughts?

    Jeff,
    What is it that I am looking for?
    It is a Hamilton bimetallic cut balance used up until the 992E came along. I think I see a gold strip on the pallet bridge but other than that everything looks normal?

    Can’t see clearly... for me - it’s either missing a cap jewel setting or it has been filed down to clear the balance after a pallet arbor/balance staff) repair...

    Very weird!! As I see it, the pallet bridge extends way under the escape wheel and the pallet pivot is in the silver circle. I suspect this is a replacement pallet bridge modified for this watch. I would like t see the lever

    What I think - you can see the escape wheel all right - it does not extend anywhere...

    Also - what's with the silver circle? The pallet bearing is the jewel right next to the balance rim. It also looks like the oil reservoir is on the other side (but it's not clear), so probably there used to be a cap jewel. The silver dot (not seen clearly) might be a plug or a reamining bit of screw in the hole that was once used to secure cap jewel setting.

    In this case this should be a 21j watch.
    The actual shape of the cut-out on the pallet arbor matches the shape of the gold cap jewel setting used in these watches.

    Would be much better to have the balance cock and balance removed to be able to give a decent assessment, on first look and with the restricted view it looks more like someone's backyard bodge job.

    Of the research and development purpose a mock-up is not usually this crude, not even for the era in my opinion, a better view would be much more beneficial.
