Send in your watch to Rolex USA servicing in either Dallas, NYC or at the Authorized Service Centers in San Francisco or Chicago and you'll be given the option for a new dial and hand set...all with luminova rather than the Tritium you've got now. It will cost extra on top of the servicing, and you'll also have to deal with Rolex USA refusing to work on your watch with a modified bracelet, so be sure to remove it before sending it in and they'll also quote an outragious price to replace that.
Reluming a dial can be done, but there are very few skilled people who can accomplish the goal without the dial coming back looking like a bad lume job. You can also seek out a good dial refinisher who will re-do the dial and lume, also with Luminova because Tritium isn't used any more.
But, when you begin the discussion about replacing a dial, even with factory replacements from Rolex, you'll ignite the discussion about diminishing the value of the watch for the purists who feel that any updating will destroy the integrity of the watch as a total piece, and thus destroy the future value as a collector's watch.
I personally don't subscribe to that for watches like the Tudor sub from the 80's and 90's. They're great watches, and their values have held up to some degree as the scarcity increases, but thinking that you're going to fund your retirement and your kids education with that particular watch is faulty logic, in my opinion. I fall into the camp that says if you want a watch to function with good timekeeping and glow in the dark lume, and it's not some rare, vintage specimin, then you should let the watch get updated with factory parts and let the watch do all it can do. I'm one of those who just doesn't see the utilitarian value in a scruffy watch with yellow, crusty and faded lume and hands that have crumbling lume.
But others will chime in with their opinions and you'll have to be the ultimate judge of where you want to take your new timepiece.
