Cobalt

The assistant

The watch is the button. The app does the work.

Press, speak

From the watch or from the app: the agent understands your request and picks the right action.

It acts in your apps

Music, messages, calls, calendar, directions: the compatible and connected services are shown in the app.

Everything is filed

Your notes and your voice commands are organised, and the actions taken are shown in chronological order.

We do our best to keep this site accurate and up to date. It can still contain a mistake, and we change it as the project moves. If you spot one, tell us.

Privacy policy

This site sets no cookie and loads nothing from other companies: no analytics, no advertising, no embedded video. So there is no consent banner. Here is the little we do handle.

Content missing

Who receives it

Hostinger, which hosts the site and our mailboxes, Brevo, which sends our news, and Google, which keeps the waitlist. We don’t sell your data and we don’t pass it to anyone else.

In your browser

If you switch language with the FR / EN button, your browser remembers that choice so that you get the same language next time. This choice stays in your browser and is never sent to us. Nothing else is stored there.

Your rights

You can ask us for a copy of your data, have it corrected or deleted, object to its use, and withdraw your consent at any time. Write to jean@cobalt-watch.com: we answer within a month.

If you think we handle your data badly, you can lodge a complaint with the CNIL, the French data protection authority.

The app

The Cobalt Agent app has its own privacy policy, because it handles something else: your voice notes. It is on its own page.

Notice about Casio

We are independent. Cobalt Watch is not affiliated with Casio Computer Co., Ltd. or with any of its subsidiaries. Casio has not endorsed or sponsored our products or this website.

The names. “Casio” and “F-91W” are trademarks of Casio Computer Co., Ltd. We use them for one reason only: to say which watch the CB-91AI board is made for. When a Casio watch appears in a photo or a video on this site, it is there to show that compatibility.

What we make. The CB-91AI is an electronic board that we design ourselves. It replaces the board of a watch that you already own. We don’t make the watch, and we don’t sell Casio watches.

Modifying your watch. Fitting the board means opening and modifying your watch. You do it at your own risk. It ends the manufacturer’s warranty on that watch, and we can’t be held responsible for damage done to it while fitting the board.
