Black polished GO components
I'm always looking to learn more about the innards of these complicated machines. I heard it said that black polishing is one of the most exemplary forms of movement finishing. I am wondering which components are given this treatment in a Glashutte Original. I believe the screws are black polished prior to heat blueing and the GO website claims the swan necks are as well.
This brings me to my GO Panograph; I am still relatively new to very high end pieces but parts like that curved piece (right above the balance) providing tension to the pivoting train that engages the chronograph clutch, the top surface of the column wheel and the top of the bridge over the chronograph train (bottom left of picture) all seem to have an extremely high level of polish similar to the swan neck (to my eyes at least). I was under the impression that large components with black polishing is very very rare. I'm not experienced enough to be able to tell if these are merely well polished parts or if they are indeed examples of the celebrated black polishing technique, I would appreciate it if anyone could illuminate on this. Certainly the surfaces looked flawless under my loupe (don't know the magnification, its not that high and was designed for examining camera sensors)

... thats quite helpful. Of course I never expected the anglage on the bridges to be black polished. My curiosity was most piqued by that jewel cap on the chronograph bridge. That said I think the response suggests that apart from the swan neck and regula...

Black polish is very time intensive work and if it is done on any parts it will most certainly be mentioned by the manufacturer in the movement description. If they don't say anything in their sales/marketing material I would assume that it is not black p...
