I have a Heuer Pasadena which has seen better days and I am intending to 'restore' it. I suspect that the crown is not original as it appears to not be PVD but possibly painted brass. It's not signed and is rather pitted on the outer face with brass showing through. The dial has been marked, probably during an earlier service and the mineral glass crystal is scratched. However the case is very good apart from one hard ding on the edge of the bezel. Can anyone suggest a source for a crown and possibly a dial? Should the crown be signed? Thanks, Tom.
