Condition report: New old stock condition. Storage age only. The movement has been recently serviced.

This example of a Heuer Calculator Chronograph, is undoubtedly one of the best and most original examples on the market today.

 

Background to Heuer: The Heuer Watch Company was founded in 1860 by Edouard Heuer. He opened a watchmaking workshop in St-Imier, a village in the Swiss Jura region. Heuer watches soon became recognized for a high level of accuracy and workmanship. By the 1930s, Heuer was specialising in chronographs, and stop watches, becoming known as a producer of timepieces sporting events. Heuer continued with this theme, and by the 1960s had brought out various timepieces for use within the car racing world. Today, Heuer is particularly remembered for their Heuer Monaco model, which was made famous by Steve McQueen when he wore it the 1971 film, Le Mans.

 

Special notes: Heuer’s slide rule-clad chronograph, was aptly named the Heuer Calculator Chronograph. While the Breitling Navitimer (the 1806 of which shares the same cal.12 movement)  is probably the best-known mechanical watch with a slide rule bezel, the Heuer Calculator Chronograph is arguably the coolest. The large external bezel is split, allowing the inner part to stay still while the outside part can be rotated to its correct calculating position. The Heuer Calculator Chronograph was a useful accessory for occupations such as architects, engineering, and aviation.
