Heuer was one of the companies seeking to develop the first automatic chronograph, and as part of a coalition with Breitling, Hamilton, Dubois-Depraz, and Buren, introduced the caliber 11 in 1969. Unlike the Monaco – which was a completely new reference when Heuer introduced it in 1969 – the Autavia reference 1163 was introduced in 1962 as an adaptation of the Carrera, and designed as the true racing chronograph of the family. Featuring a bezel with a large tachymeter scale... – perhaps the largest tachymeter scale on a watch at the time – this watch was designed for quick reading of speed and time. It's no wonder that the legendary British driver Derek Bell is said to have picked an Autavia with this color scheme to wear on the Formula One track. This is an early Derek Bell Autavia featuring an hour register with the numerals three, six, nine, and 12. The later “Viceroy” Autavia versions made for the cigarette company had one through 12 in the hour register and painted hour markers. This is a fantastic and rare vintage "Derek Bell" and "Pre-Viceroy" Autavia, whether you'll wear this on the track or in the office.Watch is running, winds, time and date set as they should.
