This is a very cool and rare Girard Perregaux from the end 50's! It's a Gyromatic with special concave case... from the front it looks like a Patek 565 but the sides are quite different. This steel screwback waterproof case measures 34mm excl. original crown. The original dial is simply stunning! Very simple with applied steel teardrop markers and outer step. It's got an amazing cream patina. Movement is GP's Automatic Cal 900 which is working well. Attached is a cool steel period strech bracelet. You won't find another easily...

Sold.
