The Superautomatic 25

Famous for what
it stood for.

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.

Superautomatic 25 on the Hooper porthole bracelet

Whether you wear it on

The modernised Hooper “porthole” bracelet

A nod to the original Speidel from the 1970s.

Or the rugged Orca rubber strap

This watch is more than a mechanical instrument. It’s a companion.
