Zodiac Aeronaut and Aerospace GMT
Standard 3-hander watch with additional 24hr hand which rotates once every 24 hours around dial. Combined with rotating uni-directional 24hr bezel it offered a GMT-setting option. It was first seen around 1962. The calibre 75 had a 24-hour function and was used in the GMT. Some GMT models had a 24 hour movement marked 70-72.
