The lume used on vintage Rolex watches was radium-based, and radium remained the standard for nearly all Rolex lume until 1963, when growing health concerns forced a shift away from it. During the early 1900’s, the effects of radiation exposure were not well understood, and radium was frequently marketed . See more

While tritium was exponentially safer than radium, it only had a half-life of a little over twelve years. This meant that after just a couple decades, only a tiny fraction of the initial luminescence would remain. Additionally, as tritium ages, the color changes, which .

When did Rolex stop using tritium? Rolex stopped using tritium in 1998 when it was banned. Following this, Rolex started using Luminova – a non-radioactive luminous material.1963: Rolex stopped using Radium due to growing concerns surrounding the material’s health risks and switched to Tritium. 1998: Luminova, produced by the Japanese company Nemoto and Co, replaced Tritium.

Tritium is a radioactive isotope of hydrogen, which produces a phosphorescent glow when it decays. 2 mins read. Key takeaways: Rolex watches with tritium lume have designations like “Swiss T<25” or “T Swiss T” on their dials. Radium was used in early luminescent watch materials, but it was highly toxic and has since been replaced with safer alternatives.

Early Tritium dials were not identified as such until about 1962 when Rolex began to add a small round Lume plot under the 6:00 marker, sometimes called "Exclamation Dial." In 1963, Rolex marked dials with Tritium using a thin silver line.
Radium on watch dials was finally banned in 1968, and tritium took over. If you come across a vintage watch with an original lumed-dial made anywhere between the 1910s and the 1960s, it was likely painted with radium-based luminescence.
Due to the radioactive nature of radium, Rolex abandoned the material around 1963 and moved to tritium. Tritium is, like Radium also radioactive, but it has a much lower radiation as well as a shorter half-life.
Before Early-1960s: Rolex uses radium for lume (radium dials are generally marked as “SWISS”). 1963: Rolex switches from radium to tritium for lume (tritium dials are generally marked as “SWISS – T < 25” or “T SWISS T”). 1993: Nemoto & Co invents Luminova (patented in 1995).Many watchmakers used tritium throughout the years including the most recognized luxury watch brand; Rolex.
