Hailing from the 1970’s during the jet age, Heuer introduced an automatic dual-time chronograph wristwatch to cater towards pilots and travelers allowing them to keep track of two different time zones.

The first examples of the Autavia ref. 11630 GMT housed the famous cal. 11 modified with a 24-Hour GMT indication. Later examples of the reference featured yet another upgraded cal. 14. Furthermore, aesthetical features on the dial were also tweaked. From 1970 onward, the neon yellow GMT hand is fitted with a rectangular tip and the 30-minute counter was divided in 6 segments of 5 minutes each. The reference was launched with two different dial variations with the other featuring grey subsidiary dials produced in less quantity. The present example features white subsidiary dials enhancing its legibility of the second time zone and 30-minute counter.
