Catalogue Essay
Reference 3147 appeared in 1966 and was powered by a Landeron 189 caliber. The first execution had the date positioned at 12 o’clock which made it hard to read when the chronograph hand was not in motion. The second version, like the present model, was modified to accommodate the date at the 9 o’clock position, thus replacing the running seconds feature. The large portion available on the lower part of the dial is one of the reasons Heuer chose this model when the brand received commissions for commemorative pieces. Over the time of production, reference 3147 was seen displaying logos such as Volvo, Cougar or the very sought after Indianapolis 500. The present second execution Dato 45 is a very classical example, with a superb soleil finish silver dial. It is further completed by a Gay Frères double grain bracelet that gives this sporty watch a more urban look. This is a very attractive and classical watch that would fit any occasion.
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.
