I wonder if Count Ferdinand von Zeppelin understood the importance of his early scribblings in 1874. Twenty years later he must certainly have had some notion, as his ideas were patented first in Germany and then in the United States at the century's close. So successful were his designs, that his surname would become a common noun applied to all rigid bodied airships.
The timepiece draws inspiration from Britain's Hawker Hunter--a trans-sonic fighter jet that spent more than sixty years patrolling the skies from 1954 to 2014. The prototype for the jet, which used a newly minted Rolls Royce Avon Turbo Engine and a swept-wing design, broke the world record for air speed the year before it became commercially available.
Unlike the Flieger, there is a degree of tactical sophistication in the pilot's aviation converter. It has the appearance of a complex dashboard instrument that you might actually find in an airplane. But in reality the bi-directional friction bezel used to operate the slide rule is deceptively simple.
