01 — The dawn

It starts with a sliver of light.

A 1,200-nit LTPO panel engineered to meet the sun at first light — and leave it behind after dark.

02 — The signal

A pulse you can finally feel.

Clinical-grade heart, oxygen, and ECG sensing that runs continuously — quietly, always, in the background of your life.

03 — The endurance

A week of life on one charge.

A custom energy core that sips power while you live large: ten days of real-world battery. Zero anxiety.

The features

Engineered to disappear.

Every component earns its place — or it doesn't ship. Six details that make the Lumen One feel less like a computer and more like a companion.

Lumen Display

1.4″ LTPO AMOLED peaking at 1,200 nits. The first screen that truly vanishes in direct sunlight.

10-Day Battery

A custom energy core that outlasts your entire week — then keeps going through the weekend.

Clinical Sensors

ECG, SpO₂, wrist temperature, and heart-rate variability in one always-on sensor stack.

Titanium Forged

A single billet of Grade-5 titanium, diamond-cut down to 32 grams. Featherlight, fortress-strong.

Dual-Band GPS

L1 + L5 precision that holds a clean line through canyons, forests, and the city's glass maze.

Lumen OS 3

Five years of software updates, and health insights that learn your baseline — not a generic score.

Why it feels different

We didn't design a computer for your wrist. We designed the most personal object you will ever wear.

  • Sapphire crystal, 9H hardness — immune to keys, walls, and everyday life.
  • One billet of aerospace-grade titanium, cut from a single block.
  • 3.2 mm thin. 32 grams light. Forgettable — until you look down.
  • Five years of Lumen OS, shipped to your wrist the day they land.
