• Upcoming updates
    Over the next couple of weeks we will be performing software updates on the forum. These will be completed in small steps as we upgrade individual software addons. You might occasionally see a maintenance message that will last a few minutes at most.

    If we anticipate an update will take more than a few minutes, we'll put up a notice with estimated time.

    Thank you!

I have an early, circa 1855-56, Boston Watch Co. watch with the CB, but admittedly it was upgraded by Waltham early on.

Jon, no thank you. I just wanted an approximate year, i.e 1864-1865 etc. My guess was that they were first used on the higher priced watches {Appleton Tracy for example} as opposed to the Ellery models, etc. but I wasn't sure.

This AT&Co was made in December 1858 and has the compensated balance as well as being listed as having one in the records. It is also a 16 jewel example (4 1/2 pairs).

Page 20 of Ehrhardt Vol. 1 there is a line that reads ...

"All of the early 1857 Models have solid steel or gold balance wheels, with the first expansion balance appearing at about Serial No. 5541."

Also if I am remembering correctly, there is a photo in one of the Ehrhardt Indicators of a Waltham at 5K serial number with a compensation balance.
