Saying that Heuer Autavia chronographs reference 3646 (two register) and reference 2446 (three registers) are currently amongst the most sought-after and coveted vintage chronographs is definitely an understatement, and finding a model in such a condition provides a certain sense of exhilaration.

Launched in 1962 under the new leadership of Jack Heuer himself, the Autavia’s name comes from the combination of the words Automobile and Aviation and the first Heuer model which was given a name.

The present reference 3646 called “Big Subs” due to its oversized subdials is what aficionados refer to as 1st execution dial and 2nd execution hands. As part of the earlier models, the present lot features a 30 minute chronograph counter whereas later models had 45 minute counters. Also of note is the fact that this particular watch features what is known as the 'type 2' version bezel, differing from the 'type 1' which has a 'no lume' triangle at 12. As the 'type 2' came out a few years later than the watch, one can only presume it was replaced during a routine service.

The dials of the 1st execution Autavia chronographs (made until about 1966) featured luminous markers and oversized numerals at 12 and 6 o’clock providing for a theatrical and visually arresting result. The present lot also has the particularity of having thin luminous inserts as used towards the end of the first batch of first execution reference 3646 Autavias.

The present Autavia in overall excellent condition ticks all the boxes for the savvy collector: seductive design, wearability, rarity and superb condition.
