Would it (2254/2255) last all night long like the Monster?
Yes and be brighter after 6 or 7 hours.
Don't get me wrong, I know the Monster is good, much better than any Speedmaster* or skeleton hands Seamaster but the sword hands model is just better still in terms of persistence and legibility. I know of nothing better.
*I haven't tried a silver snoopy or CK 2998 as I don't like them when the lights are on.
If you like lume, check out the newer Seiko Tuna dive watch, they are .... CRAZY. I have the SBBN031 and it bright!
Besides bright lume material, its just the matter of real estate. If it has more room for lume material, with bright lume material, it will be brighter.
Ahh, we long for the good ol' days of radium!
