The "seamonster" at the caseback is not a monster... According to Omega, it is actually a Sea Horse... Go figure..
Anyway, abt the lumes on the dial, the previous regular Seamaster Bond ref 2531.80 did not have the steel rims but instead had the white borders around it. I actually prefer it without the steel rims. But note that the gen Seamaster 007 edition 2537.80 had steel rims around the lumes on the dial, similar to the newer co-axial Seamasters.. Other than my regular SMP rep, I also have the rep Seamaster 007 edition, indeed, that one has steel rims around the lumes while the regular SMP does not.. I prefer the lumes on the regular SMP without the steel..
