Firmware Update
Update your watch firmware and image resources over USB or Bluetooth.

Connect watch opens the device picker. The name filter shows names starting with this text, including watches with a unique suffix. Matching is case-sensitive; leave it empty to show all devices.
For your first Bluetooth connection, enable Pairable in Settings → Bluetooth on the watch and accept pairing on your computer. Use a browser with Web Bluetooth support, such as Chrome or Edge.
For USB, open Apps → Update on the watch and enable USB, then connect using Chrome or Edge on desktop. USB updates are faster than Bluetooth.
If the watch is not responding, hold the two right buttons for 25 seconds to enter MCUBoot recovery. On older firmware, enable Bluetooth in the watch’s Update app if automatic setup fails.

How updates work
Choose a release or CI build, or open your downloaded firmware ZIP in Firmware package. Hardware is detected when the watch reports it; otherwise select it manually. Update firmware keeps your current image resources. Choose Update firmware + resources when the new version changes icons or graphics. Both actions restart the watch. Bluetooth reconnects to verify the result; over USB, reconnect to check installed images.
