Omega Seamaster Cosmic Owner Review : Elegant, endearing and reliable

This Omega Seamaster Cosmic has been part of my life for over 20 years. I bought it at auction, where it was in a lot of about ten watches, for €20! It was a different time... This is a Seamaster Cosmic ref. 166.036 tool 107 from the mid-60s. Case diameter of 35 mm (without crown), but on my 18 mm wrist, it doesn't look small at all. Crown signed but not screwed, Omega caliber 752 with automatic winding, gold plated. The watch is entirely original, with its plexiglass engraved with the logo in its center. It is as I bought it, and still in very good condition. The dial is splendid and the indexes shine brightly. Omega quality is evident! I have never serviced anything in over 20 years, and the previous owner had been dead for 30 years (the auction was the widow's estate) which means the watch has not been serviced for at least 50 years. I wear it very little (4/5 times a year), but as soon as I wind it, it goes off at 1/4 turn. I just ran it through the timegrapher: it only loses 10 s/day on several positions. Omega quality shows!!
