What does luminous dial mean?
Luminous watch hands have been in use since around 1910. Pigments based on photoluminescent material (like strontium aluminate) are what are most commonly used for watch lume today. This non-radioactive material is painted onto hands, numerals and dials, then glows in the dark by absorbing light then re-emitting light.
How long do luminous dials last?
While promethium doesn’t cause its phosphors to break down as quickly, it has an extremely short half-life of just 2.62 years. In other words, a watch featuring promethium on its dial is only likely to glow very weakly, for a few years.
Why are watches luminous?
For their wearers, however, radium watches were comparatively safe, since the radiation emitted by radium only amounted to a few centimetres in the air and was already blocked by the watch case. To this day, there is a rumour that the bones of the Radium Girls are glowing in their graves.
What is lume on a watch?
Lume is a short term for the luminous phosphorescent glowing solution applied on watch dials. There are some people who “relume” watches, or replace faded lume. Formerly, lume consisted mostly of radium; however, radium is radioactive and has been mostly replaced on new watches by less bright, but less toxic compounds.

What makes luminous dials glow in the dark?
Types of Luminous Dials. Many vintage watches, especially military watches, have gold or whitish colored “paint” on the hands or on the numbers on the dial. This paint is quite likely made of a phosphorescent compound mixed with radium. This causes, or at least used to cause, the numbers and hands to glow in the dark.
When did they start using luminous watch dials?
Luminous radium dials were first used around 1910 before the dangers of radioactivity was fully understood. Radium dissolved in water was even sold as a health tonic and said to increase your energy levels and cure diseases. After WWI and through out the 1920s, radium dials became popular and were widely used on watches and clocks.
What kind of luminous paint is on a watch dial?
There are three primary ways of identifying what kind of luminous paint is on a dial. First, beginning in the 1950s or 1960s, watches that used tritium would either have two small “T”s on the bottom of the dials by the 6 or have “T<25” labels. The “<25” means that there was originally less than 25 milliCuries of radioactive tritium.
What are the sizes of Lume dial watches?
