We put the sensor inside the clasp.

No bigger than a standard watch clasp. Nothing visible from the outside. Nobody knows it's there, including you.

Signal proven. Independent testing by CSEM, the Swiss research centre, confirmed research-grade heart rate variability at our sensing position: beat-to-beat error under 10ms against a 20ms target.

Built by people who've done it before. Engineered for manufacture with a team whose members built the first generations of the Oura ring.

Protected. International patent application filed.

Experienced leadership. Decades across technology licensing, health-sensing wearables and investment governance.

Proven founder. Gabriel Drogon built Steel Reef, a precision watch-component brand with over $2m in sales to 15,000 customers in 70+ countries.

Heart rate. Sleep. Recovery. Stress. Steps, activity and calories.

Enough to understand how you're actually doing, and to make better decisions about it. 

No screen, no buzzing. It's in the app, privately, whenever you want it.

Find My Watch. See where your watch was last connected to your phone, so you know where to start looking.

Every other wearable asks you to change something. Wear a second device. Put it on every morning. Accept how it looks.

Most people won't, for long. It ends up in a drawer, or it stays at home on the evenings out. You lose exactly the moments that would have told you the most.

Nobody leaves their watch at home.

A sleep band comes in the box, tool-free to swap, so it carries on overnight.

Adapters move it between the watches in your collection in seconds.

Waterproof. 10+ days on a single charge. Built to stay with you.

We didn't set out to make another wearable. We set out to make the one you already wear do more.

Living well shouldn't mean changing how you live. The future of this technology isn't another object to put on. It's disappearing into the timepiece you already choose, and already love.
