Concept smartwatch

Halcyon One

Time, beautifully kept. A titanium watch that tracks your heart, closes your rings and lasts a week on a charge.

From ₹24,900

Design

Titanium outside. Sapphire on top.

A 10.7 mm case milled from grade 5 titanium, with a domed sapphire crystal that curves into the edge so there is no seam to catch on a sleeve.

Health

Rings that close themselves.

Move, exercise and stand goals fill in as your day goes on. Heart rate, blood oxygen and sleep stages are measured quietly in the background.

Battery

Seven days on a single charge.

Fourteen in low-power mode. And when it does need topping up, ten minutes on the puck gives you a full day back.

Finishes

Four finishes. One you.

Pick a colour and watch the case and strap change.

Built to be worn, all day and all night.

A concept product made for a portfolio. The bag works; checkout does not.

Questions

Does it work with Android and iPhone?

In this concept, yes: it pairs over Bluetooth with either and syncs health data to the phone's own health app.

Can I swim with it?

It is water resistant to 50 metres, so pool and open-water swims are fine. Not for diving.

Which size should I pick?

41 mm suits wrists up to about 17 cm; 45 mm has a larger screen and a slightly bigger battery.

Is this a real product?

No. Halcyon One is a concept made to show web design and 3D motion. Nothing on this page is for sale and no payment is taken.
