rolex oyster radium removed | rolex fluorescent material rolex oyster radium removed 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.

In the early days, Rolex used radium, a highly radioactive material, to create the glowing effect on their dials.

The tritium dial was relumed in the late 60s or early 70s with radium. The radium was applied on top of the tritium. I had no idea for the nearly 30 years I wore it day and night until earlier this year.

I don't know that you need to "refinish" the dial, just have the existing radium removed and the dial cleaned. That maintains the nice, aged look while reducing your radiation exposure. Few collectors will quibble over it. Once that's done, the radiation level should drop down to negligible.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.

The lacquer component of the luminous mixture "gases out" or evaporates over time due to a normal chemical reaction caused by exposure to oxygen and humidity. The gradual disappearance of the lacquer bonding component leaves the Radium in a more vulnerable state with each passing year. a general overview that's useful for Rolex collectors to understand the differences of luminous, their used time period, the influence it had on the condition of the dial and what typical details one has to look for when analyzing a vintage Rolex. The radium lume obviously can't be replaced, but you have some choices. You can have it stabilized and leave it as is. You may be able to find someone to attempt to fill the missing sections with a compound of matching color. You can have the lume removed entirely from that hand and replaced with color matched lume. Radium luminescence was soon replaced with tritium, a much weaker radioactive material that was safe to use on watch dials. Tritium was used by Rolex into the late 1990s, and older dials that use tritium lume often fade to a tan color on the indices.

Following the guidelines of Section 16, relays 1/2 can use a current setting of 30% (150 A) and a TMS of 0.2, using the EI characteristic. Grading of relays 3/4/5 follows the same procedure as described for the phase-fault elements of these relays.
