Of watches I currently own:

Officine Panerai Luminor GMT 088 is the brightest great lumed markers broad hands and lumed second hand.

Ball "Mad Cow" with tritium tubes is the best after about 4 hours,

Of everything I've owned:

1. Ball COSC Diver -- lots of lume to rival Superluminova but in always equally bright tritium tubes. Hands down winner.

2. Girard Perregaux Seahawk II Pro 3000 -- best Superluminova thanks to broad sword hands, lumed centered second hand, and large markers with differentiation at 12, 3, 6, 9.

3. Panerai 187 Diver - thick hands like my current Pam 88, great indicators, lumed second hand.

4. Omega Planet Ocean 45.5 mm Chrono.

My current Rolex with the Maxi-dial is the best of the Rolex line, but not as good as a Seiko Monster.

Also, I owned a Nautic Timer with the full dial lume. Those don't work nearly as well after a few hours as the initial lume would lead one to believe.
