At the beginning of the 70’s, Bulova put into the market new tuning fork watch for diving, it was a Snorkel.
This fantastic tuning fork watch is interesting in that on the dial has an sign and that is 666 feet, or 200meters.
Many brands that fit declare water resistance avoid to writing this figure, so they wrote about the approximate values because of the significance of that number (666) …
Tuning fork movement is maximally precise, the inner bezel is rotating by upper crown… today this model reaches a high price, of course if it’s an authentic one.
Today, a re-issue has been made, it just reminds on original, but the movement is completely different.
