Technically, the Heuer, including the slide rule, works perfectly and has recently been serviced: (282°; +20s/d).
The watch shows hardly any signs of wear. There are no deep scratches, dents or similar, the glass is scratch-free.
The Heuer watch brand, now known as TAG Heuer, has a rich history and is known for its innovative watch models. One of Heuer's special models is the "Calculator" chronograph, also known as the "Heuer Calculator".
The special thing about the Heuer Calculator Chronograph is the unique design with a slide rule on the outer edge of the dial. This calculator allows the wearer to perform various mathematical calculations including multiplication, division, speed calculations, conversions and more. The Calculator was introduced in the 1970s and was particularly popular with pilots, engineers and mathematicians as it offered a practical and useful function right on the wrist.
The Calculator model represents Heuer's commitment to technical innovation and functionality. It was one of the first mechanical wristwatches to integrate such a calculator, providing a practical solution for complex calculations on the go. This chronograph was an example of Heuer's advanced engineering and shows how the brand always strived to develop watches with additional useful functions and applications.
Today the Heuer Calculator is a sought-after rarity among watch collectors and lovers of vintage watches. Its unique design and technical innovation make it a sought-after collector's item that reflects Heuer's history and legacy as a leading manufacturer of chronographs and technically advanced timepieces.
