Universal Genève Aero-Compax

About this reference

The Universal Genève Aero-Compax reference 22477 was produced during the 1940s, specifically appearing in catalogs around 1941 through the mid-to-late decade. Collectors prioritize this reference for its 37mm stainless steel spillman-style case and the manual-wind Calibre 285 movement. The dial configuration features four sub-registers, including a "memento" dial at 12 o'clock intended for pilots to record a specific event time using an independent crown at 9 o'clock. This technical complication distinguishes it from standard chronographs of the era. On the secondary market, examples typically trade between $10,000 and $20,000 depending on dial originality and case sharpness. A notable production detail is the transition from early radium-luminous leaf hands to later syringe-style hands. High-condition examples with unpolished cases and original "tropical" or silvered dials have reached the upper end of this range at specialized watch auctions.
