Heuer 3500 Calculator for "Beechcraft" Ref 110.633

This is a very rare Heuer 3500 Calculator watch for "Beechcraft" , which is an American manufacturer of aircrafts. The Beechcraft logo is prominently displayed in the middle of the original deep blue dial. This watch is a calculator chronograph with precision slide-rule and is powered by a caliber 12, 17 jewel automatic movement. The condition of the watch is exceptional. We believe the case to be unpolished and the dial and hands totally all original. What is also very cool about this watch is that it has the numbers on the back case which would match the wing number of the aircraft it belonged to.
