1961 Girard Perregaux "Tropical" Gyromatic

Go back 10 years from now  , before Hodinkee and vintage being trendy, real collectors knew what a tropical dial was. It wasn't brassed out dials , excessive moisture , scratches removing lacquer. True tropical dials  sold for the same price or less and they were around from many makers. I have owned 7 different Polerouters with tropical defects from manufacture making some go choclate to others consellation. Here is a true tropical dial Gyromatic from 1961. I have only owned another tropical dial Gyromatic and that was also from 1961 in solid gold and the dial had turned the same choclate color.
