The Jaeger LeCoultre Atmos 2 required our standard overhaul (cleaning, oil, bellow test) and we found the bellow to be flat. This is likely all this Antique Atmos will require to run and keep time, we are currently allowing it to run and doing minor regulation adjustments. This is the way we insure timekeeping, and in the event that timekeeping is sporadic on an Atmos, it is the indication that we will need to go back and replace the wire. 
The bellows had previously been replaced from the original mercury sealed unit, with the gas version of bellow. This was flat with pin hole in the back, and we were able to repair it and refill it. We do the bellow refills in shop and here is a link with more information about that process Atmos Bellow Refill
There was some patina and pitting on the case that no matter how long I buffed, it wouldn’t go away and some worsened (very minor). I also plated the metal in 24k Gold twice as long as I typically do in attempt to cover the slight patina but they are still faintly visible (only is certain light). I did not strip and plate the balance wheel of this Atmos because it would result in the loss of the black etching lines unique to this model. There is slight bubbling on the balance wheel, but it is not an eyesore in any way. 
I have tried to photograph this and it is hard to even capture it with camera. We photographed the Atmos in several different lighting styles. Here is a look at the Jaeger LeCoultre Atmos 2 on a shelf with two other Atmos Clocks:
