Welcome, nice example. Patina concerns me, how does the movement look? Did it clean up well when it was serviced?
You'll find MANY threads on Constellations here.
Thank you, yeah... I don’t know what’s going on with the patina. I imagine someone “cleaned” it during service. Movement looks great and it actually keeps very good time !
Appears like moisture contamination around 11-12 oclock especially, and the (uninformed) harsh cleaning was trying to remove it and you get the results you see all over the dial.
But, who knows....that's why I asked about the movement condition.
