In 1975, a timepiece surfaced from beneath the cinematic waves—quietly, confidently, and without pretension. It wasn’t a watch chosen for its fame. It became famous for what it stood for: courage, craft, and character.
The Alsta Nautoscaph ‘Superautomatic’ was worn by Matt Hooper—played by Richard Dreyfuss—in JAWS. But before the screen immortalised it, the Superautomatic was already a tool trusted by those who ventured beyond the shoreline, into deeper waters and wilder horizons.
Half a century later, we bring you not a reissue—but a reimagining.
