c.1973 Heuer Calculator Automatic Chronograph

Lot No.: 821

Sold for (£): Unsold

In 1972 Heuer presented a new model with a mathematical name of 'Calculator'. With the Heuer Calculator the consumer had a clever mathematical instrument at hand which allowed for the calculation of difficult mathematical operations with just a few clicks of the watch.

This Heuer Calculator Automatic chronograph is in a stainless steel square/tonneau case with a straight starburst finish and polished sides. The two calculating circles consist of a fixed inner scale and rotating outer ring. The black dial has 12 hour and 30 minute subdials. The date is at 6 o'clock and it has luminous baton hour markers. The movement is a calibre 12, originally designed in collaboration by Heuer, Breitling, Hamilton and Buren. It was the first automatic chronograph designed. Condition is fantastic and is simply the best we have ever seen. Perfect collection piece.
