Not sure what happened here ? I don't remember a SS F300 having a WG bezel, the 1301 EQ has one, allegedly.
Do you know the case number? There were solid gold models certainly but not to my knowledge any 198.XXX f300s with a gold bezel on a steel case if that is what you are asking.
Possibly. That is presumably a gold capped model, some (all?) capped Omega’s have solid bezels but the question was about white gold bezels, can’t think of any of those.
Hence my first reply but the second one could help someone bumping into this post at some point. And yes CD is "Coiffe d'Or", i.e. Gold Capped.
