What I believe I have here is a 1968 Snorkel, however it does not say "Snorkel" on the dial. Everything else points to a Snorkel, but I am unsure of the variation. Date code definitely puts it at 1968.
Some Snorkels have "Selfwinding" on the dial and mine has "Automatic".
Was Bulova inconsistent with what was put on the dials or do these slight variations appear at certain times in the manufacturing run?
This has a tropical dial, creamy lume that still glows, "ballerina" case back. I picked it up yesterday and have been wearing it ever since. It's keeping great time.
