    Luminous phosphorescent glowing solution

    Apologies if it has been discussed on here before, but what are people’s thoughts on why the lume on a Seiko, costing a few hundred pounds, seems to be far superior to a brand new Rolex at 8 grand?!

    Because the Rolex costs less to build than the Seiko, despite the retail price.

    All said in jest of course.

    I suppose both are glowing at exactly the rate their designers have wanted.

    Why do you think Rolex owners want to carry a torch on their wrist? Just think of all the secret service agents wearing a Rolex.

    But brighter lume would be useful for signalling the mini sub for the pick up when being chased by evil henchmen.

    OP Rolex and others have proprietary lume mixes that are based on Luminova. I think luminova was was developed in conjunction with Seiko (I am sure someone will correct me if I am wrong) and Seiko are still developing it (their new stuff is super bright) as such they always have the latest / best version.

    You also have to consider the colour of light of that is emitted by the lume mixture.
    Rolex use a blue tint, this is less bright to the eye than standard green (there are a few articles on the web to explain this if you are interested)

    Lastly the size of the hands and dial plots along with the thickness of the coating also plays a part.
