This just arrived and was really very disappointed to see it has some kind of bluish-purplish gunk all over the sides and back.
Hopefully, it can be cleaned off.
Zenith Defy Surf reference 01.1370.380, caliber 2572PC (automatic with quickset date), stainless steel case with screw-down crown, mid-late 70s.
