Description
This is a very good HEUER vintage CALCULATOR Chronograph ref.110.633 in stainless steel with original Corfam rally
watch strap which fits the watch perfectly. Manufactured in the early/mid 1970s with the legendary automatic caliber
12 Heuer build in. The large oversize Heuer Chronograph Calculator was to compete with Breitling’s large oversize Navitimer
ref 1806 Chrono-matic which was also fitted with the caliber 12 inside. The watch had limited appeal to the watch buyer but
was used by Ferrari Racing Team Engineers and executives on the paddock during the race as a tool watch. It allowed quick calculation
of fuel and weight distribution needs at the time when electronic calculators were non existent.
