The Carrera reference 1153 was part of the trio of models Heuer used to launch the Calibre 11 automatic chronograph movement in 1969. The other two being the Autavia “Siffert” and the Monaco. The first examples of these three models had the model name above the date and the word Chronomatic above the Heuer badge. Only a handful of these were produced as Heuer rapidly sold the Chronomatic name to Breitling.

The present example is the earliest known reference 1153 without the Chronomatic name and with a new dial layout. It features a first execution dial (with 3, 6, 9, 12 markers on the subdial on the left) with plain steel hands and luminous material as well as black stripes in the center, which match the hour markers. Also of interest to note is the earlier 50-200 tachymeter scale crystal ring and an early example Mk2 Gay Frères bracelet dated 3.69 fitted with HLC end links.

Residing in a wonderful unpolished case with original lume to the dial and hands this timepiece is the epitome of the Carrera design and will certainly quicken the pulse of the discerning collector.
