1940s Girard-Perregaux "Aero-Compax" Stainless Steel 38mm Spillmann

This is a very rare 1940s Girard-Perregaux "AERO-COMPAX" ss 38mm Spielmann case. It is a special chronograph with a memento dial, which is a dial for storing time, and the memento dial at 12 o'clock is operated by a special crown at 9 o'clock. It is a very rare watch with a Spielmann case, although there are many variations of the Aerocompax, including non-waterproof, waterproof and universal. It is a precious gem that the dial of the fourth eye that has changed with age with good texture attracts originality, and the Spielmann case with a sense of gravity of 38mm over attracts a wonderful presence.
