History of the line
Contrary to the most widespread account — long repeated by the brand itself and by many retailers — which would place the Sea Wolf's debut in 1953, alongside the Rolex Submariner and the Blancpain Fifty Fathoms, more recent historical research on period advertisements and trade magazines places the actual launch later: a first mention appears in a November 1957 advertisement for the "Pharoan" line, with the official presentation at the Basel Fair in spring 1958. Even with this correction, the Sea Wolf still belongs to the first generation of dive watches designed for a wide audience, reaching the market just a few years after its more famous rivals.
The first series, with a stated water resistance of 100 metres (probably overstated according to some watch historians), introduced a rotating bezel numbered anticlockwise, designed to work as a dive timer rather than a simple hours scale: a solution that would later become standard on most subsequent Swiss divers. The dial focused entirely on legibility underwater, with generously luminous indices and hands and a distinctive marker at 12 o'clock.
Between 1959 and 1960 came a second series, with water resistance raised to 200 metres and new triangular indices (the so-called "pie-slice" indices), an update that consolidated the Sea Wolf's reputation as a credible diving tool and not just a showroom sports watch. Since then the name has remained the backbone of the Zodiac catalogue, revived in countless variants up to the current Super Sea Wolf collections.

For decades Zodiac and many retailers described the Sea Wolf as a 1953 contemporary of the Submariner and Fifty Fathoms. More recent research into period advertisements and trade magazines, carried out by independent watch historians, has shown that the most likely launch date is 1957-58: a small example of how, even in an industry built on precise dates, the marketing story can long prevail over archive documents.
