Is this real...? Expert advice needed.

[Ds650quad]

All,

I'm a little stumped, and looking for some group wisdom. Not totally certain whether I have a fake, a Franken, or the real McCoy.

Here's the info that I've gathered thus far.

Tudor Oyster Prince 34
Self Winding
17 jewel

reference # shown is 7909...(which I believe correlates to a Tudor sub)
serial # shown is 154064...(which I believe correlates to the 1950's)

Lug holes are present
Lugs to Lug measurement is 19mm

Dial looks to be in excellent condition...(possibly refinished?)

Luminous markers are present at each hour...(and are still glowing very brightly, especially noteworthy considering its supposed age)

Photos are attached. Your thoughts, ruminations, and opinions are appreciated.

If I've left out any pertinent info, please ask.

Any/all help is much appreciated.
