Carbon Tourbillon

A sporty carbon watch face with a heart you can see beating: a big round window at 6 opens onto a mechanical movement, and its tourbillon cage turns once a minute, step by step, like the real thing.

The dial

• Carbon: marbled forged carbon, or the classic 2x2 weave.
• A black tachymeter bezel with a true scale, from 500 down to 60.
• Applied steel batons filled with lume, a double one at 12 - or Roman or Arabic numerals.
• Bold skeletonized hands with lume and coloured tips, and a seconds hand in the same colour.

The panel

A dark window under 12 reads your day's steps, your heart rate and one more line of your choice: the watch battery by default, or any data you pick. That line shows its app's own icon, or the app's name where it sends no icon; set it to Empty and the panel keeps its first two lines, clean.

Make it yours

• Accent: red, yellow, blue or lime.
• Carbon: forged or classic weave.
• Hour marks: lume batons, Roman or Arabic.

Always-on

The screen goes dark: the hands and the hour marks as dim outlines with their lume, and the window's ring.

To customize, touch and hold the watch face, then tap Customize.

The heart rate shows "--" until your watch has a reading. Not a medical device: the readings are for everyday information only. Works on watches with Wear OS 6 or later. Made in Watch Face Format: nothing to install on your phone, no permissions, no data collected.
