Nomadgiles' one: Uncommon, beautiful, Chronometer, and... A Girard Perregaux. Add the cherry on the cake, a superb condition. Et voilร ! Best, Nicolas ...
The matching coloured date disc is a great touch. These late 60s / early 70s HFs had a few fume dials - this one with grey / brown for steel cases and a more overall brown fume for gold fill cases. Not many HFs about and very few fumes. Cheers.
