·Well its an assembly, albeit a possibly quite valuable one - well the dial is.
It is a 105.003 dial, highly sought after, and an asymmetric case - and who knows what movement is inside, lets hope its a 321 otherwise that valuable dial might have suffered some minor damage, as its not designed for an 861 movement.
Getting it back to any sort of correct condition will require a lot of parts, and that is after you decide what you actually have. It could be a 69 case and movement with the wrong dial, or a 65 dial and movement in the wrong case.
Either way, if it were me, I would find a bezel, service it and not change anything, keep the history.
Next step is to see the movement, the number and the inner case back.
Well said, and I got a kick out of your politically correct, “it’s an assembly”, back in the day we called them Frankenstein watches. It would have been nice to see the back of the caseback since the jeweler opened the case to view the movement.
Another puzzle, if you believe the father in that he bought new and never had serviced.
Hopefully we will find out the rest of the story
