I think it might have been one of your posts that had the detail of the bezel that made me go down to my AD at the time and get one. I already had a regular marine diver and was looking at the Aqua Perpetual. However I fell in love with that magical blue wave on the bezel.
Going with the blue theme - I also foundĀ great Montblanc pen that carries the same blue hue...
Enjoy
