Best luminous watches

[clockboy]

Found this interesting article about luminous watches:

Using  photoluminescent material to show the time in low-light conditions is a practice that has been employed since the development of the earliest wristwatches.

Originally, radium was used on hands and indexes, which had the benefit of a bright and long-lasting glow, counterbalanced by the disadvantage of being highly radioactive and a major health issue for those who applied it.

In the 1960s, radium was replaced by the much safer, yet still radioactive, tritium, which was phased out in the 1990s when alternatives like strontium aluminate (in the form of Super-LumiNova) came to market.

The idea behind practically all forms of ‘lume’, though, is that they absorb light during the day, store it and then emit it in the dark. The most common colours are blue, green and white, but this is by no means all that is available. Usually coating hands and indexes, the more adventurous manufacturers - like the ones listed below - have found ways to add light shows to dials, bezels, cases and even straps.

A good example is the following beauty.See pic

According to Ball watch, the self-powered micro tubes that have become its trademark are 100 times brighter than standard luminous coatings, and, although the glow will gradually fade over time, a replacement dial will easily solve the problem. The illumination is achieved through H3 tritium gas, safety-sealed in mineral glass tubes that are coated with a luminescent material. And nowhere is the light brighter than in the recent Engineer III Marvelight. With rainbows now a symbol associated with 2020 and the global fight against Covid-19, Ball has issued the limited-edition 40mm watch with multi-coloured gas tubes. For every piece sold, 300 Swiss Francs will be donated to The Salvation Army.

I like the watch, but not the rainbow colors...

And I was always interested in having a luminescent date wheel.
