2001 DJ - why Tritium dial & Luminova hands?

[Magic-Matt]

Hey guys!

Noticed a few days back that my 2001 P series DJ (avatar pic) has the Tritium dial that has virtually no lume power left, but has Luminova hands! Weird right? I can clearly see the difference when I shine a torch/UV lamp on the watch and view in the dark, hands glow bright, markers nothing at all until your eyes adjust hours later throughout the night!

Ive read some posts on Rolex oddities such as this - like Tritium marked dials around the 98-01 period actually coming out the factory with Luminova paint and even Luminova dials with Tritium hands!

To sum out, what are all these inconsistencies and what's likely to be the story with mine (if anyone can guess it). I purchased from 1st owner that had never touched the watch except for one AD service. (Heard the AD sometimes replaces hands without notice) but not the dial, perhaps the most logical explanation?

Be interesting to hear your thoughts as not sure whether it would be more suited to the watch to stick some Tritium hands on it, or try and get an identical dial with Luminova , i.e. SWISS MADE printed at the bottom.
