I search in the dark. I've seen this mikroregulation until now at movements of Longines and G.Thommen (Revue) but both doesn't match. Nice quality movement in all points. You've removed the case. May be a view on the dialside is possible and helps.
That's what I think about today:https://www.youtube.com/watch?v=vlUGeY7MWVo
I must say that I doubt that it is a common version of the movement. Rather, it is probably a "Jules Jurgensen style" adaptation of a common but different looking ebauche. As such, I think that a look at the keyless works will be necessary to get a clue as to the original movement maker.
You go to a watchmaker to see the back of the dial.Then I take pictures and I will return.
I was a the watchmaker.On the back of the dial does not write anything and has no stamp.Under the dial, the movement has two series.The first number is 33 and the second series has 6 digits.
Can anyone had this movement.It is a movement of quality and are surprised that the manufacturer did not write the name or company stamp.
However, maybe someone knows who made this movement.
In that case, I suspect it's an Unitas Cal. 33 in the savonette ("hunter") version with a bridge modification. Here is the lepine (open face PW) version without any modifications:
bidfun-db Archiv: Uhrwerke: Unitas 33
As you can see, the exact position of the gears in relation to the rest of the movement, the exact shape of the lever cock under the balance plus some other features (position of some of the screws, especially the two that hold the dial feet) match. For absolute confirmation, compare the keyless works under the dial.
Thank you very much.
Hello. Doesn't this seem too early for the Unitas 33? The regulator and hairspring stud style also 'seems' (!) to speak of another Maker...of course, once we can see under the dial...!!
