Rolex Submariner 14060 T-25

[MK1222]

Hi. I'm new to the Forum and looking for some help. I recently purchased a pre-owned Submariner Reference #14060 from an authorized dealer. The Serial # begins w/a P which I believe dates the watch to the year 2000. However, at 6 o'clock on the dial is the word Swiss followed by t25. In doing some research it appears that the T25 identifies watches with Tritium Lum, which I believe was replaced by Super Lum in 1999. That said, I'm concerned that the watch I own has this on the dial if it's of 2000 vintage. Hoping for some expert feedback on why this might be. Thank you.
