Rolex 6303/645 information

[extermin8tor]

Hi everyone,
I was recently in a small Indonesian village and found a watchmaker who was keen to sell some projects.

In his small little kiosk right by a rice field as a Rolex Jean Claude Killy dato-compax in parts (dial quite worn) but otherwise complete. He wasn't willing to sell it as it belonged to a rich customer from Jakarta.

He sold me a 6303 oyster perpetual with a black dial with a 645 movement.
It was ticking however dirty.

The movement as it turns out was complete but with a rooted barrel cover, I have ordered a 600 barrel cover which hopefully fits. Couldnt stake the cover closed.

I am wondering which year rolex started printing SUPERLATIVE on their dials?
It appears to be a 1954 or so watch, however to my knowledge should only say CHRONOMETER OFFICIALLY CERTIFIED.

It appears re-dialed as the finish is very good and fresh. There is also no lume pips on the dial despite it saying T SWISS.

Should I get it restored back to saying 3 words without SUPERLATIVE???

I paid about $550 USD for the watch so it wasn't a huge investment, however keen to get it working well.

I noticed the back cover is a 6505 as well which is odd. It is a bubbleback cover and it fits well, is it a Franken? Or could Rolex Indo/singapore/wherever have done something funny back then?

If anyone knows what style cover the 6303 should have please let me know.

I have fitted a Tropic 12 crystal and kept the original in a sleeve tucked away.

Cheers
Alexei
