In the early days, Rolex used radium, a highly radioactive material, to create the glowing effect on their dials. In this journal entry, we will take a closer look at the history of Rolex's use of luminescent materials, including radium, tritium, and LumiNova, before exploring Chromalight. Rolex Oyster Perpetual 116000 with the Green Super-LumiNova Prior to the widespread implementation of photo-luminescent material, Rolex used a radioactive compound called Tritium to make their hands and dials glow in the dark. Since Tritium is radioactive, it will glow whether or not it receives any light exposure; however its ability to glow is limited by the radioactive half-life of the material itself. While vintage Rolex watches first used radioactive radium followed by tritium to illuminate in low light, modern Rolex watches use Super-LumiNova or Chromalight to supply them with their luminescence. Read on to find out the similarities and differences between Chromalight vs. Super-LumiNova on modern Rolex watches. Most Rolex watches using tritium have the marking "T Swiss T" or "SWISS -<25" at 6 o'clock to indicate it uses the radioactive material, as seen in the image above. Rolex Luminova Rolex introduced Luminova for its watches in 1998. The company Nemoto & Co. Ltd invented the material in 1993 and patented it in 1955.

RADIUM The first luminous material used in Rolex watches was radium; and it remained the standard until 1963. Before then, the effects of radiation exposure were not well understood, until the highly toxic material caused radiation poisoning among factory workers. I had an opportunity to play with a Geiger Counter. I tested vintage watches that use different radioactive lume: Rolex Explorer 1016 with Tritium lume, Seik. Despite being substantially safer than radium, tritium was still radioactive, and as a result, many watchmakers of the time (Rolex included) marked the dials with an indication of the level of radioactivity emitted by the watch, such as "T Swiss T", or "Swiss T<25". Tritium was far from perfect, which led Rolex to search for a better alternative. In case you don't know, the GMT's Bakelite bezel was radioactive (there's some debate as to exactly what in the bezel was the biggest culprit here) and Rolex recalled the watches, offering to retrofit them with aluminum bezels. This is one reason why original Bakelite GMTs are relatively rare today.

October 14, 2019 Radioactive Rolex Rolex I'm sure you remember the scene in Dr. No, the first outing on the big screen for Sean Connery's James Bond. 007 is off to search Crab Key, the island lair of the titular villain, to investigate the origin of a number of radioactive rock samples. Most Rolex watches that used tritium were marked with T Swiss T or Swiss T at the base of the dial by the 6 o'clock mark. Not only that, as it's a radioactive substance, Rolex marked the level of radioactivity using a '<25' in the same location. Rolex Milgauss ref 116400GV with Luminova. Luminova (1998 - 2000)
A new study from the good folks at the University of Northampton has shown that we all forgot one essential fact: radium decays to radioactive radon gas, which is readily inhaled and will in sufficient doses significantly increase the risk of lung cancer. Rolex Chromalight and luminous materials. The first luminous material that Rolex used for its watches was radium. The problem with tritium is that it is both highly radioactive, but also has a half-time which means that the lume will eventually die out on a Rolex watch. But one of the main switch was health concerns, in particular for the.

Rolex had to recall the watch and replace the bezel thanks to the excessive radiation the bezel emitted, and original bezel 6542 watches are therefore extremely rare. However, if the bezel is original it's basically just as radioactive as the day the watch was made - an important caution for any collector who owns one.. Prior - 1953, The early age of Rolex luminous, used on their pocket watches, early oyster cases, bubble backs and radiomir Panerai's. 1953 - 1956, When Rolex introduced the world their sports / utility / tool watch concept with radium Submariner, TOG, Explorer & GMT Master. 1957 - 1960, When Rolex lowered radiation and chanced dial.
