Catalogue Essay
Many famous Grand Prix drivers of the 1960/70s wore Autavia models. Amongst them was Jo Siffert, the Swiss double Formula 1 Grand Prix champion. Affectionately known as "Seppi" to his family and friends, Jo Siffert used to wear an Autavia 1163 tachymeter scale, white dial with black registers and date. Almost a year after his tragic accident during the 1971 World Championship Victory Race, Heuer launched the reference 73663 with the so-called “Siffert Colours”. From this point Heuer collectors would use the champion’s name to describe a panda dial with blue seconds chronograph hand and black stripe markers & matching black striped steel hands.
The present lot is offered today in excellent original condition, the sunburst finish of the case is crisp and the dial is in wonderful condition. The watch is fitted with its rare stainless steel Heuer bracelet made by Gay Frères. In our view the reference 73663 are until now, undervalued treasures and avid collectors should not wait too long.
This iconic chronograph manufacturer has a long tradition of precision timekeeping. As early as 1882, founder Edouard Heuer held a patent for a chronograph watch; in 1887, he received a patent for an oscillating pinion, which is still in use today. These specialized timepieces have been at the heart of the firm's success, enabling the brand to be chosen as early timekeepers for the Olympics. In 1969, the company introduced their first automatic chronograph watch, the Monaco Heuer, which celebrated the Monaco Grand Prix. Other key chronograph models include the Autavia and the Carrera, all of which having become iconic models of the firm.
