Lume vs Lume

[PacNW]

Quick question for those in the know...I just had my ND Sub serviced at RSC Beverly Hills, and opted for a new dial as the lume was basically DOA. Did a comparison with my 2005 Exp II for brightness and it seems that the Exp is still brighter than the Sub. Could this be because of the white dial maybe being more reflective? Same charge time on both. Pretty weird-I thought the new dial on the sub would be stronger/brighter.
Thanks all for any input

i believe this is true. ive noticed that the blue colored omega smp was brighter then the black. i'd imagine that the white gmt would be even brighter

I have heard this is so, from several sources. It makes sense, I suppose...

Yes, I experienced that, too, on the White Face Cos I had. Glowed stronger than the Black Faced one I got later.

I have heard other people say that the lume on white dials is brighter but to me, they look like they are about the same.

I own a GMT 1 black dial, which had superluminova applied to it from its most recent service, and an Explorer II white dial, already with superluminova, and they seem to both glow at a similar brightness with consistency.

Superluminova lume is a function of three items:

1. Color perception of the human eye;
2. Total surface area painted;
3. Number of coats or thickness of the applications.

Charging the Superluminova with a flashlight "excites" the molecues and makes them rise, giving off light as they settle. The more, the better.

Color perception depends on the environment. Allegedly under water, the last color the human eye sees is a shade of blue.

On the surface a shade of greenish/yellow is supposed to be the most observable. There are charts which show these.

Choice of Superluminova, however, also plays into what color looks the best, e.g. snow white, when looking at the watch in daylight.

Best lume of any watches I've owned are the Ball watches with glass tubes filled with tritium gas, both safe and with greater lasting quality over the hours, with no need to "charge" them at night.

After that would be my former GP Seahawk USA 71, then former Omega Planet Ocean 45.5, and now my Panerais.

The best lume of any Rolex I've ever owned is my new GMT Master II- C "Green Arrow" with the Maxi-Dial. Very acceptable.
