1974 Bulova Oceanographer in NOS drop dead gorgeous condition. Blue and white rotating bezel is perfect, not a scratch anywhere on this beauty. Back is only marked with 'Bulova', the s/n and "Stainless Steel 666 Feet. Original matching all stainless bracelet also marked 'Bulova'. Dial is marked Bulova Snorkel - Automatic 666 Feet. Not sure if the numbers on the back tag have any meaning.

Some Snorkel ads here. The second looks a bit like Geoffs watch.

The last Bulova ad naming a watch "Snorkel" is from 1968. In the 70's they advertised watches with Snorkel on the dial as Oceanographers. We HAVE ads is all I'm saying.
