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. Later GMT watches used the calibre 75B with a quickset date function which involved pushing the crown, a counter-intuitive move.
Note all GMT cases have chamfered bezels which distinguish them from otherwise identical Seawolf cases
