The
Yema watch company was founded in Besancon, France, in 1948.
Yema became James Bond's first movie watch (Dr. No, 1962).
It
was for the 1989 International Transantarctic Expedition that
Dr. Jean-Louis Etienne, team leader (with Will Steger), commissioned
Yema (of France) to manufacture a wristwatch which would allow
the explorers a way to find their bearings via the sun; the watch
displays mean as well as sidereal time.
Only
1500 units were made, at an original retail price of US$1500.
