Around 1968, Heuer introduced its very first GMT chronograph model, which used a variation of the short run fourth execution Autavia dial in a screw-back case. A noticeable feature of this particular type of dial is the lume hour Tritium markers that are applied directly to the dial, reminiscent of the very first Autavia watches (but without numerals). The 24 hour hand enabled the reading of a second time zone in conjunction with the bezel. This new feature was obtained by using a modified Valjoux 72 calibre, known as the Valjoux 724 movement.
 
This beautiful GMT is in great condition. The case has no scratches, beautiful colored dial, and a slight faded bezel. Its previous owner is the well known Jeff Stein, Heuer collector and and the founder of on the dash. It comes on a thick leather racing strap with retro Heuer buckle.
