Please help me ID the specific model of this Rolex dated from 1955 due to caseback personalization.

Thank you,

Hi
looks like model 6106 or 6108. Introduced in the 50s
Take a look between the top lugs, it should have the model number.
Between bottom lugs is serial number for dating.

I agree with Adam..

and want to add that the dial on the watch is want we call an early "Explorer dial" with the 3-6-9 number configuration. The dial numbers made it easy to read in low visibility conditions. I would say this watch can be classified under sport watch category.
Similar watches as the one posted were worn by mountaineers of that time period for extreme use.

I see one screw on the rotor has gone..

Nope, that is one of the greatest misunderstandings of Rolex.
Only one screw is EVER used.
Below the rotor there are 5 screw holes, when you wind the rotor onto the shaft only 1 screw hole will line up snugly, and that is the one the the retainer screw goes into.
Its a VERY smart idea, as you can not know exactly where the rotor will stip when screwed down onto shaft, but with 5 holes below, one ALWAYS lines up.

Nothing missing, two screws means a bodged repair.
