joshuar 0 Report post Posted September 25, 2015 Once upon a time, I owned a no-date Sub, which I traded for a GMT Master. Then I acquired a wife and kids and the Rolex had to go. I'm looking to replace it, but I remember loving the tritium feature of my earlier watches. What do I need to know about the Super Luminova that Rolex currently uses?

Kris33 0 Report post Posted September 25, 2015 Rolex now uses Chromalight, not Super Luminova: - It is blue when illuminated, white when not - It is not particularly bright, particularly when the eyes are still adjusting - It illuminates the watch all night long - It does not cause cancer like tritium (as far as we know) Quote Share this post Link to post Share on other sites
setover12 0 Report post Posted September 25, 2015 What is there to know? Expose it to light and it will glow in the dark. I believe it will glow a blue colour, and last a decent amount of time in comparison to lume of old. The lume on my Tudor Pelagos is out of this world, and I think it is the same stuff Rolex use.

Erren7 2 Report post Posted September 25, 2015 Apologize... we both had typos... meant Chromalight. Nonetheless, while some speculate Chromalight is Superluminova, Rolex claims it to be proprietary, so I am sure it is (as this is a legal term). Several watch reviews highlight this fact. Also, I did not claim tritium caused cancer to the watch wearer, but it does cause cancer like any radioactive material can. Quote Share this post Link to post Share on other sites

mytime 4 Report post Posted September 25, 2015 Don't know if it lasts longer but on my Explorer, Explorer II and Tudor Ranger, the lume lasts all night. Quote Share this post Link to post Share on other sites
uBeast 0 Report post Posted September 25, 2015 +1 for the new blue lume lasting a long time. I had a small overlap with owning my SubC ND and Planet Ocean. The blue glowing indicies last for hours. The green on the PO kept it's charge, but not nearly as long. Quote Share this post Link to post Share on other sites
