A hand-finished skeleton movement, suspended in sapphire and grade 5 titanium. This is Strata.
The Philosophy
Nothing Superfluous.
True luxury lies not in excess, but in the deliberate curation of the essential. Strata strips away the superfluous to expose the pure, beating heart of horology.

Architecture
The Mechanism Is the
Dial.
Every gear, every bridge, every jewel serves a purpose. Suspended within its sapphire and titanium housing, the movement hides nothing — because there is nothing to hide.

What They Say.
“Under a loupe, the interior angles are flawless. The anglage alone tells you where the 400 hours went.”
The Horology Times
“Strata resists every trend — no faux patina, no borrowed heritage. Just architecture, honestly expressed.”
Watch Journal
“The most compelling independent debut in years.”

A Letter from the Founder
Why Strata Exists.
I spent ten years restoring vintage grand complications — watches made by hands long gone, for people long gone. What stayed with me was never the gold, or the names on the dials. It was the honesty of the work underneath.
Strata is my attempt to build with that honesty today. The traditional techniques, none of the nostalgia — no faux-vintage, no compromises. One watch at a time, start to finish, until it is right. Nothing more, and nothing less, than the pure expression of mechanics.
