Hi there, greetings to all
« on: January 31, 2013, 09:23:00 PM »
Hi, I am new to this forum and I need some help from senior members.
Why most rolex subs were marked SWISS MADE,  and some marked SWISS - T <25 ?

Hi remontang,
Welcome to Malaysia Watch Forum.

Back in the day Rolex, like most of the other watch manufacturers, used radioactive Tritium as the Luminescent material on the watch dials. These watches came with the T<25 designation on the dials.

After 1998 Rolex switched to the modern non radioactive Luminova to provide the night glow on the watch dials. Hence we no longer see T<25 label on contemporary Rolex timepieces.

Hope that answers your question.

 :Cheers:

I believe that T<25 means the watch uses no more than 25 millicures of radioactive Tritium for its lume material, which is a very safe level...
