Install the Free face first
The key unlocks Pro inside the Free edition, so install the Free face from Connect IQ and make it your current watch face. Pro keys exist for the faces listed on the Pro key page, and more faces are added regularly.
Find your watch code
On your watch, open the Free face settings. At the bottom of the menu, Pro key shows your 8-character watch code. The Get Pro screen shows it too, with a QR code that opens the purchase page with your face and code already filled in.
Buy your key
Open astra-watch-face.com/pro-key, type the name of your face and your watch code, then pay by card, PayPal, Apple Pay, Google Pay, WeChat Pay or a local method, depending on your country. Your key appears on the page and arrives by email.
Enter the key
On the watch, open the Free face settings, choose Pro key and enter the 10 characters; dashes are optional. In the Connect IQ app, you can also open the face settings and paste the key in Pro key. Pro unlocks right away, no internet needed.
One key, one watch
A key works for that face on that watch, even after a reinstall. A key typed on another watch is refused, because each watch has its own code. New watch? Email contact@astra-dev.fr with your order number and the new watch code.
