- 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.
- Tritium is a radioluminescent material that emits less radiation, making it a safer option for watch lume.
- Rolex T Swiss Made T watches are sought after by collectors, and their prices can vary depending on factors like rarity, condition, and provenance.
A Glowing History: From Radium to Tritium
The Dangers of Radium
In the early 1900s, watchmakers began using luminescent materials to make their timepieces more legible in dark environments. Panerai first developed a process for creating luminous markings in 1915 using the highly toxic substance Radium. Unfortunately, many dial painters from this era suffered severe health issues and even death due to their exposure to this dangerous material.
The Rise of Tritium
Following the discovery of Radium’s toxicity, watchmakers turned to tritium, another radioluminescent substance, for a safer alternative. Today, the completely health-friendly photoluminescent Superluminova is commonly used to provide optimal legibility in modern watch dials.
Decoding the Designations: Swiss T<25 vs. T Swiss T
Rolex watches that feature tritium lume bear designations like “Swiss T<25” or “T Swiss T” on their dials. These markings indicate the type of luminescent material used and the amount of radiation emitted by the watch.
Swiss T<25
The “Swiss T<25” marking indicates that the watch is Swiss-made and contains an amount of tritium that emits less than 25 mCi.
T Swiss T
The “T Swiss T” designation shows that the watch is Swiss-made and contains an amount of tritium that emits less than 7.5 mCi.
L Swiss Made L
When you see the “L Swiss Made L” designation on a watch dial, you can be sure that the lume material is photoluminescent, like Superluminova.
Rolex T Swiss Made T Price: Factors Influencing Value
The value of a Rolex T Swiss Made T watch can vary significantly depending on several factors, such as rarity, condition, and provenance. Here are some key aspects to consider when evaluating the price of these watches:
Rarity
Rolex T Swiss Made T watches are sought after by collectors due to their historical significance and unique luminescent properties. Watches with rare variations, limited production runs, or unusual features will typically command higher prices.
Condition
