From 01/01/1999 Rolex has begun to use "luminova" instead of tritium on dials,
so new watches are simply signed "swiss made" instead of "t swiss t" or
"swiss t<25" or "t swiss t<25".
"t<25" simply means that each gram of tritium in indexes and hands has a radio
active emission lower than 25 milli-curie ; in other words one gram of tritium
is 40 times less radioactive than a gram of radium.
