Titanium Components
Core components machined from space-grade titanium. Titanium was chosen over other materials for its strength at a fraction of the weight, which is the only way a this complicated watch can turn feel light on the wrist.
Hand Assembley
Every EW01 is assembled by hand, then regulated by hand to within ±8 seconds a day, far tighter than the movement’s factory standard. Before it’s approved to ship, each piece is individually inspected, with the dial, the armillary motion and the finishing checked one by one.
Proprietary
Complication
The complication that drives the armillary and the retrograde minutes was designed for the EW01 alone. Every gear and axis was developed over two years of prototypes, then mounted onto a proven automatic base so the invention never compromises reliability.
Precision Machining
Case and components are CNC-machined, with added locating points so every part aligns to tight tolerances. The hour discs carry concentric guilloché rings, and the steel case is brushed and polished by hand-finishing to catch light from every angle.

The Foundations
Beneath the design sits a foundation chosen for reliability, then refined by hand.
Automatic Winding
Powered by the motion of your wrist, with manual winding through the crown.
Hand-Regulated
Adjusted by hand to within ±8 seconds a day, well beyond factory specification.
42-Hour Reserve
Keeps running for nearly two days off the wrist.
Domed Sapphire
Scratch-resistant sapphire crystal, domed high over the armillary.
Aerospace Titanium
Grade 5 titanium used in aerospace design chosen for strength and weight.
Exhibition Caseback
Open to the rose-gold rotor, a window into the inner engineering of the watch.

FAQs
The hours orbit with the armillary and are read at the top of the dial along with the minute markers. The minutes are shown on the retrograde arc above, from 00 to 60. The dominant arrow indicates the current active hour marker.
No. It’s an automatic mechanical watch, wound by the motion of your wrist.
Yes. It’s natural aventurine, a precious natural gemstone that is estimated to be a million years old, formulated deep within the Earth’s crust, so every dial is unique.
Each watch is regulated by hand to within ±8 seconds a day before it ships.
Every hand painted element on the watch including the black markers as well as moon all illuminate in the dark when it gathers sufficient charge from light itself.
