Watches tested:
*Seiko Black Monster
Getat 45mm sterile radiomir homage
Fortis Spacematic
Nautica chronograph watch
*Casio MDV-106 200m Duro
*are diving watches, so according to some ISO 6425 (buy 4d!) standard specs, it is supposed to have the following:
Uni-rotating bezel with marking every 5 mins
Distinguishable minute markings
Adequate visibility in complete darkness at 25cm from eyes (LUME)
Indication that watch is running in darkness (using lume in second hands)
Magnetic/Shock/Chemical resistance to a certain degree
Strap/Bracelet durability must be able to tahan pulling to a certain level without spoiling.
Blah blah..digress and digress.
Anyway back to the lume, these are photos immediately after luminated and around 3 mins later.
Monster first:
Seiko's lumibrite is really bright and torch like after charging, even normally, it gets lumed for the rest of the night and remains very very visible.
Many people say that lumibrite is Seiko's name for C3.
Next up is radihomage:
The radiomir homage is not half bad as well, this watch actually is very readable in the dark, uses superluminova.
Now Spacematic is the only Swiss powerhouse here:
I think this watch is not build for its lume, the lume was ok for a 5 year old watch and the lume just fades very quickly. Despite so, it still sports a very very very faint glow in the dark for a long while, probably due to the age.
Now for Nautica:
Its not going to be spectacular and for a watch its age and this is the only non-watch brand watch brand against Seiko, Casio, Fortis and Getat.
Lastly the Casio duro 200m, its predecessor uses a electro-backlit dial.
It seems bright but I would put it at the same level as the Getat. But the lume lasts longer but fades quickly to a dim and stays that way. Actually the longest lasting would be the lume dot on the bezel.
There you go, Seiko is the lume champion of cheap over the counter watches and stays true to the ISO rating of being called a divers watch.
