lumilune

Watch dials glow at night, markers bright with the sweet haze of lum. All watch lovers respect the night glow of a fine watch. It is probably the most useful property a watch can contain, but what makes it happen? Most watches currently use a substance called superluminova. This grade B substance was the second choice to the previous tritium (radioactive) substance used for years. Watch makers applying tritium basically started getting cancer of the mouth from holding brushes there over long periods of time. Superluminova does a nice job, but will not hold the charge tritium does, still it is safe. Watches I have witnessed with tritium never really impressed me much, SL is fine, check a Omega Seamaster for the best lum of any watch, all SL. Ball watches and a few others still use tritium encased in tubes, they just don’t light it up like a nice SL dial, too many safety standards ruined tritium forever. Just cup your hand and be the judge!
