The “Compax” was introduced in 1935 as the world’s first chronograph wristwatch with hour and minute registers. Members of the armed forces appreciated this new style for its functionality. The models were available in different case materials and forms, as well as a variety of dial layouts using the names ‘Tri-Compax,’ ‘Uni-Compax,’ and Aero-Compax.’

The Aero-Compax was first launched in 1941, and this wonderful example from 1944 demonstrates how a steel Compax case would have looked after leaving Universal’s factory. The watch has this amazing feel of having lived the best possible life, as we hardly see this model in such crisp and hardly worn condition. The dial shows a warm ageing with crisp printing, adding to the desirability of the piece.

The present example displays an interesting “memory” register at the 12 o’clock position of the dial. This feature allows the user to establish a start time by engaging the crown on the left hand side. For pilots and military personnel, this was often used to mark the start time of a mission. Presented in overall excellent condition, it is hard to believe this watch is over 70 years old, making this one of the finest examples of an Aero-Compax one could hope to own.
