I've been wanting to do this for a while now and since there wasn't much to do yesterday, I decided to conduct a lume comparison test using 3 of the most 'lumed up' watches I have. I was quite surprised how it turned out. Read on to know how it went down:
1) Pyrolume 43mm Prototype Watch #12
2) Seiko Orange Monster
3) Omega Seamaster GMT
4) Mossy Oak (MO.322.214.171.1241)
Though the Mossy Oak has tritium tubes instead of lume on its hands and markers, I decided to add this to compare the efficiency of tritium vs lume paint.
I left the Pyrolume, Seiko and Omega lying on a desk, in a room with the lights on, for about a couple of hours. I left the Mossy Oak lying in the watch box since it doesn't contain any lume paint that requires charging.
The test was conducted over a period of 3 hours. Photos were taken after 60 and 180 minutes.
The photographs were taken using the 'bulb mode' on my camera and keeping the shutter open for 5 seconds.
To compare the result, I checked the luminosity in photoshop. Luminosity of 100 = pure white, where as 0 = black. This isn't necessarily the most accurate method, but it gives a pretty good idea nonetheless :)

Here are the watches, just before the lights went out:
With the lights off:
Pyrolume : 83
Seiko OM : 89
Omega GMT: 81
Mossy Oak: 73
Pyrolume : 17
Seiko OM : 17
Omega GMT: 18
Mossy Oak: 64
Pyrolume : 03
Seiko OM : 05
Omega GMT: 15
Mossy Oak: 67
The tritium, as expected stayed pretty much at the same level throughout the test. As for the other 3, I was expecting it to be a close call between the Seiko and the Pyrolume to take the top prize. Though the level of luminosity was similar in both the watches throughout, the Omega Seamaster was the most readable after 3 hours, thus making it the overall winner! :)
