I have narrowed down my vintage watch search to an Omega Constellation with a 564/5 movement stainless steel "C" cushion-case; or a vintage Girard Perregaux 18k yellow gold.
Both seem to be between the $600-$900 range which is my budget. I do not know the best vintage movements for Girrard Perregaux or if they would rival Omega's at the time, but I would prefer for the GP it to be 18k.
Update: Vintage Tudor's also might be an option!
Which one of these would you go for and be the better purchase?
