The Luminous Evolution Of The Rolex Replica Watch Water Ghost

Radium was discovered by the Curies 120 years ago.

And it should be World War I that pushed this discovery into the Rolex Replica Watch industry.

In the early 20th century, military pocket watches with black dials and significant hour markers were ordinary. It is often used for coating hour markers and hands and is made of a mixture of radium and zinc sulfide (Zinc sulfide), the earliest luminous material on watches.

Although radium’s radioactivity proved harmful as early as the 1920s, it remained the material of choice for luminous materials for quite some time.

Radium

Early Submariners and their luminous materials are no exception. The picture below shows the first generation of Submariner Ref.6204, its bright material has been mottled, and the honeycomb surface has also been eroded, “a face is full of traces of years”.

Tritium

The safety of radium luminous materials has always been a significant hidden danger. Rolex swiss models finally gave up in 1963 in favor of Tritium. Although Tritium is also a radioactive element, it is less radioactive and has a short half-life.

The picture below shows the 1966 Submariner Ref.5513, which is already made of Tritium luminous material. The bet at 6 o’clock has the words “Swiss – T<25”, which means that in the bright fabric, the emission of tritium gas is less than 25 millicurie (Millicurie).

Since Tritium has a half-life of only 12 years, its luminous life will be depleted after a few decades. But what is interesting is that the time scale gradually turns yellow with the baptism of the years. If a gold frame does not surround it, it is trendy today.

Luminova

Rolex is known for its durability, but Tritium does not last as long as the Rolex Replica Watch itself, and Rolex is always looking for better alternative materials.

In 1998, high quality fake rolex began to use the Luminova luminous material supplied by Nemoto and Co., which was later upgraded to Super Luminova, whose main component was strontium aluminate (SrAl2O4). It is a photoluminescent material, which can emit light for several hours after being exposed to sunlight for a few minutes, and has a longer lifespan than Tritium.

The previous generation of submersibles used this type of luminous material.

Chromalight

The current new Submariner has Chromalight luminous coating.

This new material replaced Super Luminova in 2008 and first appeared on the Deepsea submersible. Unlike Luminova’s green glow, Chromalight is blue in the dark and lasts longer.

So far, we can appreciate this charming touch of blue whenever we are in the dark.
