Last UG bought from the amazing 10H10, thanks again, it's a beautiful Polerouter 1955 with a 138 SS caliber
So, I ended up picking up the aero compax from the bay that is referenced in Sala (page 303). as discussed here : https://omegaforums.net/threads/universal-geneve-watches-on-ebay.3584/page-204#post-1097401 The Dial has severe grading , especially from 12-3 but I think its beatiful, in line with my other UG's and thus have no reason as of now to believe it to be a redial (there were some doubts in the eBay thread) - maybe the experts can help? My first aero and I am super happy
