Just stumbled upon this post ... interesting.
First of all, nice Sub ... I too love the clean & more balanced 2-liners.
Not sure if you are aware of this, but there was a small batch of "T <25" dials, which used Luminova instead of Tritium. Rumor has it that Rolex had leftover T <25 dials during the 1997/98 transition therefore put Luminova on these dials to clear up inventory.
I believe what you have, is this relatively rare example. .. because Tritium today would never glow this brightly in the dark. I have two U-serial GMTs that does the same.
Congrats !
