While the Aero Compax model is most commonly known to be a Universal Geneve watch, there is actually a very rare variant not known to many. This example is indeed an Aero-Compax, but instead branded by Girard Perregaux.
The Aero Compax was a very unusual watch developed by Universal Geneve. It is a chronograph wristwatch but with an additional subdial at 12 o’clock featuring a second clock. This clock does not work but acts as a memory clock, intended for people to remember appointments and important times. Using the crown at 9 o’clock the user can set any time he or she wishes.
This example has aged very nicely with the dial turning into a champagne colour. This alongside the blued hands and yellow lumes makes for a very attractive watch. A nice quirk about these cases were the round ‘mushroom’ pump pushers. If you look closely the top pusher cap sits very flush with the bottom of the pusher and little details like this make me love what I do.
Everything is pretty much exactly the same as you would find in a Universal Geneve Aero-Compax, but as we all know about vintage, it is about rarity and the one branded by Girard Perregaux is a quirky variation that adds much more desirability to it.
