When did Rolex stop using Luminova?
The lume used on vintage Rolex watches was radium-based, and radium remained the standard for all Rolex lume until 1963, when growing health concerns forced a shift away from it.
Does Luminova fade?
Luminova and (Swiss) Super-LumiNova are not prone to discoloration or ageing over time. They don’t fade, nor will interact with moisture.
Does Rolex use super-Luminova?
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.
How long does Rolex Luminova last?
However, they are radioactive and have a half-life of slightly over 12 years. This means the intensity of the tritium-powered light source will gradually fade, generally becoming too dim to be useful after 20 to 30 years.
Is LumiNova safe?
Modern solutions are much safer to use. The two popular types of watch lume nowadays are Tritium (radioactive but safe to use) and Swiss Super-LumiNova, which is completely non-radioactive, non-toxic and based on a formula consisting of strontium aluminate.
How long does Panerai lume last?
If it’s modern lume then the lifespan is virtually the same as the watch but tritium paint tends to be shot after about 10 years and tritium tubes start to loose their potency after about 12 and often need replacing at about 25 years.
Why does my Rolex not glow?
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. This means that as Tritium ages, its ability to glow will diminish until the point that it ceases to glow at all.

When did the Rolex Submariner 1680 come out?
Rolex introduced the Submariner 1680 in 1967 and continued to manufacture the reference until about 1980. However, the “Red” Submariner with its characteristic red name on the dial was only produced for the first part of the ref. 1680’s production run, until approximately 1975.
What’s the difference between Red Dial and white dial in Rolex 1680?
With the ref. 1680, we can really split the reference in two between what are known as red dials and white dials. Only applicable to the stainless steel models, the reason for the distinction is down to a single line of text – the ‘Submariner’ name.
Which is cheaper the Rolex 1680 or 5513?
The ref. 5513 was therefore the cheaper option and the one with fewer lines of text on the dial. Rather than replacing those models, the ref. 1680 became the third Submariner reference available. In terms of essential styling, there was nothing to choose between any of them.
What are the inserts on a Rolex red?
The inserts on the Rolex “Red” Submariner ref. 1680 vary depending on the production year. Up until 1969/1970, therefore in the “Meter First” family, the insert is the famously rare “Long 5” (this component alone can cost up to €2,000 depending on the condition).
