Wow, this has got to be the Omega Aoratos ( αόρατος ). It's the rarest model Omega produced, i've never actually seen one before...
Not sure if anyone cares but on mobile the picture showed up as: Which I believe would be a bumper type omega from the 1950s.
It is also, I believe, a screenshot from La La Land. I saw that shot on another forum discussing Ryan Gosling's watch in the movie. Sent from my iPhone using Tapatalk
