Universal Geneve Aero Compax 22290 SS case is in outstanding condition, 34.5mm without crown. Even though this is a mid sized case, I find this reference to be my favorite, as I consider it to be the "classic" Aero reference, and the one you often see used in UG advertising. You can see some radium decay on the dial around the numbers, however this is especially visible in high magnification photos, it is not so readily visible with normal viewing, in which the dial appears quite attractive. The watch received a full service 18 months ago, everything is working as it should. I would love to do a trade on an Omega Speedmaster 60th anniv (full set), but if you have other trade proposals, feel free to reach out. I have many references here on OF and also other platforms.
