Swiss-T<25 MEAN..... Some said confirm Tritium treated???? Andt some said dial with white gold ring is confirm luminova????? than why they still put Swiss-T<25 if it is luminova????? Rolex experts please help. Thank you Heng.

so gruesome that if I posted a pic, I would definitely be ban for life! I can't let that happen. Sorry

Up to 1997, indices used Tritium, on both matte dials and glossy dials with WG surround indices (during the mid to late '80s was the switch from matte to glossy dials). Service dials replacing old matte dials will have luminova after 1997. There was a var...
