I think that the divers logos are great. But... I would not be surprised to find out that these are 'protected' like the British Broadarrow sign. Having said that, a restyled (?) diver's helmet would look great too. That would implicate that the text needs to be in a circle near the outer edge of case back, eg. like the text on a Seiko 6105.
A little off topic perhaps: Bill puts the # on the case back. I think it would be nice to put the # between the lugs, leaving more space for a nice case back design.
Back to the circular serpent I posted earlier. It's a complicated design with lots of details. Perhaps one of us on the forum is some kind of wizz with CAD drawings, Photoshop etc and he (or she!) can simplify the orginal picture, so that it can be placed on the back of the new watch without braking the bank...
