The blue highlights on these watches are luminescent,
...so a dark environment at depth would in fact improve contrast, not hinder it.
The colours at the shorter end of the wavelength spectrum should really penetrate less well through water, not better - due to a phenomenon known as Mies scattering. I'm not sure why the opposite is true here.
Why did they use blue instead of violet? My guess is that while violet can be perceived by the human retina, it's not well perceived. The retina has three different types of colour-sensing cone in it, each of which is maximally sensitive at a particular wavelength. The shortest of those three wavelengths corresponds to a colour we call "blue".
Hope this helps.

SIHH 2007 report: the new range of Jaeger-LeCoultre men's diving watches ...
When SIHH 2007 is closing its doors in a few hours, I'm happy to share with you the following report about what is a new range of watches from Jaeger-LeCoultre. All fall and winter long we've had rumours about a new diving watch, neo-Polaris or not. This ...
No there isn't
and of course, not really necessary. No real need for 1000M rating too, I guess.... Cheers, Asi
Is blue last colour visible and so what anyway?
I don't believe blue is the last colour visible, data I've seen from Googling is saying violet. And that agrees with my notion of the absorption corresponding to wavelength, i.e. the last colour of the rainbow wins. Is it about colour though? I'm not so s...

Women have more than Men....no?
Tony, I believe that women have 4 types of cone cells whereas men have only 3 types. Is this correct? So, how does a light blue dial colour work for female divers; if there were such things? Do they just divide the spectrum into 4 sections equally or do t...
