Question re: dial of my 16750

[ikanbilisclub]

Hi all, my first post on VRF though I've been silently perusing the wealth of information here. usually more active on OmegaForums. I'm J from Singapore and I collect mostly vintage Gallet/GP/Breitling/Grand Seiko.

Wanted to ask the Rolex GMT experts' opinions on my 16750 dial.

Finally got the chance to take some macros of my 16750 that I acquired a few years back (without much prior knowledge as it was an anniversary gift and was bought from a vintage dealer in Singapore).

Its a 7.4mil serial with a Mark II dial.

My main question re: the dial is whether it has been the tritium lume has been washed off or is it still an original untouched dial?

My observations are:
- to the naked eye the hour markers appear fairly white and smooth with quite clean borders
-not much patina seen on these markers - I surmise its either the dial has been washed off lume or the previous owner wore it so much in the sun thereby 'bleaching' it in the process.
- doesn't have the puffiness/curdliness of lume that I've seen on other 16750s (at least on pics on IG and the net)

Based on the macro pics:
- there are some bumpy bits seen on the markers
- most of the dial appears dead under UV though the GMT hand lights up nicely, there are some small specks of tritium seen on the hour, minute, seconds hand as well as the 5 o clock marker (this is seen better with a loupe)

Appreciate your thoughts on this! Been bugging me for a bit as I learn more of the 1675/16750 references. Cheers!

i realise I can't attach links to larger image files as I'm a first time poster. Not sure if the picture attachments are high-res enough

Thanks all!
