Philipps unveils a fascinating piece of Rolex history, detailing how a Rolex Submariner Ref. 6536/1 received what he believes to be one of the first 'service dials' due to radiation concerns. His post, supported by a signed receipt from 1960, provides compelling evidence of Rolex's early efforts to address radium radioactivity in its watches.

The story behind the 6536/1 with III-57 caseback and 306.xxx serial is that the owner read an article in the Dutch newspaper by Schaap & Citroen jewelers asking owners of submariner to come back and change it to a less active / radioactive dial version. There where a total of 9 around. This was in the Netherlands around 1960, i have the signed receipt of schaap & citroen...during changing the dial to a lower radiated now 2 colour gilt dial, he got changed the winding crown too, old one is on receipt....;- ) Now the 6536/1 has a gilt dial with silver dept as prior it was in all gold print. These old 1 colour printed dials had a 10 times higher radiation then the later 2 coloured gilt dials. Rolex was calling in their sub owners to change the dial as first reaction of the danger of radium. This later's a kind of mixed lume is still active under light and if one doesn't know this look one could point out a relume but it isn't. It's seen on dials from '59-'60. So theoraticly the 2 coloured gilt minutetrack dials are first service and later standard in production. Once we hit '62-'63 the radiations goes down by 5 times less Swiss T<25...
first 2 coloured print...







one colour print 6536...


One the right the 2 coloured printed dial and left the 1 colour print.... As the lume was much higher one the first ones the laques of the dial is mostley damaged by the corrosion. ...

About the Rolex Submariner Ref. 6536

The Rolex GMT-Master reference 6536 is an early example of the GMT-Master line, distinguished by its smaller case size compared to later iterations. This reference is notable for its introduction of the GMT complication, allowing for the simultaneous display of two time zones. It represents a foundational piece in the development of Rolex's travel watch offerings, preceding the more commonly seen 6542.

This reference features a stainless steel case measuring 37 mm in diameter, housing an automatic movement, specifically the caliber 1030. The watch is fitted with an acrylic crystal and offers a water resistance of 200 meters. The power reserve for this movement is approximately 42 hours, providing reliable timekeeping for daily wear.

For collectors, the 6536 holds interest as an early and less common GMT-Master reference. Its position in the lineage of the model highlights the initial design language and technical specifications before subsequent refinements. Variants within this reference may include subtle dial or bezel differences, which are often points of scrutiny for enthusiasts seeking originality.

And I wanted to see Subs without crownguards...

Now I am served! Very interesting explanations, my friend. Tell me one thing. On the last pic, there is a Sub, no the left, which has almost grey indexes. Radium, or a kind of mix? I ask you because I found some Vintage Blancpain FF with the same color of indexes... Which used Radium. Wow, my friend, you will be responsible for my sleepless night. Best, Nr 86.

On the first pic, I noticed

That there was no writing at all above 6. I mean no " Submariner " written. Normal? A gorgeous pic and piece, by the way! Best, Nicolas
