Inspired by life at sea. Built with attitude.

The PS1/04 captures the spirit of a vintage wooden yacht cutting through open water — weathered brass instruments, deep navy tones, polished teakwood decks, and mechanical details shaped by adventure.

But this is SEVENFRIDAY.
So it comes with edge.

The antique brass double PVD case feels like aged nautical equipment pulled straight from the dashboard of a classic wooden yacht, while the rich navy blue dial and bronze detailing bring warmth, depth, and unmistakable maritime character.

Beneath the skeletonized layers sits the exposed balance wheel, constantly moving like the mechanics of an old marine engine beneath deck. Industrial architecture, layered textures, and smoked metallic surfaces create a watch that feels engineered rather than decorated.

It’s nautical without feeling polished.
Vintage without feeling nostalgic.

More midnight marinas.
More salt in the air.
More freedom than formality.

Finished on a navy blue leather strap, the PS1/04 balances rugged maritime inspiration with raw SEVENFRIDAY industrial DNA.

And naturally, it’s connected. Embedded NFC technology links the PS1/04 directly to the SEVENFRIDAY App for secure authentication and access to the global 7F community.

Built for open water.
Designed for restless souls.
