Skeletonized. Stripped open. Fully exposed.
The PS1/01 takes the iconic SEVENFRIDAY cushion case and tears the dial wide open, exposing the raw mechanics underneath like a machine with no interest in hiding how it works.
This isn’t clean luxury.
This is engineered chaos.
Built around a fully skeletonized five-layer interface, the PS1/01 creates insane visual depth from every angle — floating bridges, exposed balance wheel, honeycomb textures, metallic blue structural details, and industrial layering all suspended beneath sapphire crystal.
Every component feels architectural.
Every surface feels alive.
The smoky grey recyclable animation ring and metallic blue accents inject a colder, more futuristic edge into the watch, while the polished steel case keeps the entire piece grounded in raw industrial SEVENFRIDAY DNA.
Nothing here feels decorative.
Everything feels mechanical.
The exposed balance wheel constantly pulses beneath the dial, turning the PS1/01 into less of a watch and more of a living machine strapped to the wrist.
And because this is SEVENFRIDAY, the experience goes beyond mechanics. Embedded NFC technology connects the PS1/01 directly to the SEVENFRIDAY App for secure authentication and access to the global 7F community.
No cover-ups.
No fake perfection.
Just raw mechanical attitude.
Show me, don’t tell me.
