Fres Esquivillon De Choudent - Earlier than 1850

Fres Esquivillon De Choudent, we are around 1780/1790, one of the greatest Blasons of the era, among the most sought after for their refinement and for cutting-edge innovations as far as their mechanical engineering is concerned, and in this case, also a wonderful Aesthetic to make it even more exclusive.
A genuine 18th-century painting depicting two ladies of the era, with the shapes and clothing used in the Napoleonic era, and a Dove to symbolize peace.
I remind you that we are in France in the midst of the French Revolution, a subject loaded with History.
In excellent aesthetic condition the dial, which presents untouched ceramic, has only some chatter but which is not felt to the touch (no scratches); it appears more as a Cracklet effect, and as you can see from the photos it is still very well preserved.
Some signs of wear on the enamels of the painting in the back case, but small in size and not touching the painting.
The hard stones surrounding the two cases are mostly present; there are a little more than ten missing out of about one hundred in total, and potentially restorable.
Regarding the operation I wrote non-functioning, unfortunately my universal key is too thick and I was not able to wind the clock. I feel I can say and affirm that the Balance is intact and functional. Oscillating the clock cautiously, I see the balance runs for about fifteen seconds as well, until it stops due to lack of propulsion.
It could be functional but I repeat, having not been able to test it I insert "non-functioning".
Moreover my trusted clockmaker is unavailable for at least 2 weeks, and I could not have him perform the test.
It is a watch of incredible rarity, and of great prestige, with a very high intrinsic value even as a relic.
I believe the metal is gilt brass.
