Lot Essay

Heuer introduced the Calculator in 1972. The bezel on the Calculator is split so the outer ring can be rotated while the inner is stationary. The calculator can do simple mathematical equations like multiplication. It can also do more complex equations like calculate fuel consumption, speed, distance, and rate of elevation. The Calculator was Heuer's answer to the Breitling Navitimer.
