Here's a 1960s Girard-Perregaux Gyromatic Supercompressor with a compression dial in blue and orange.
Shovel hands. Original bracelet. Original polish. Cool trident back.
This beast is a solid 40mm across, not counting the crowns, by 42mm from lug to lug. Keeping excellent time. Movement photos on request.
A couple of scratches on the crystal, hard to show in photos. Nothing to detract from the appeal of this classic.
The original bracelet fits a 7.5 inch wrist. Your wrist.
