I've been looking around for a G-Shock that has tide/moon data.
Thus far I've seen the Gulfman 9100-1ER (http://www.amazon.co.uk/Casio-G-Shoc.../dp/B000VE26L6)
and the 7900-1ER (http://www.amazon.co.uk/Casio-G-7900...d_cp_watches_1)
So, a few questions:
Are there any I've overlooked?
If not which is better?
Which is better value?
Further to the last, are there any other differences between the two?
Just as an added difficulty, I live in the UK, and a fairly remote part of it at that, and as such I can't see them in the steel; so how do they wear? As an indication I've got an Omega Planet Ocean 42mm and a Seamaster 41mm, which I think are fairly ideal size. I could go a bit larger, but not much.
Over to your superior knowledge,
