Over-the-Air Updates
Always up to date.Without cables.
Your Telltime connects via Wi-Fi, retrieves the time with atomic-clock precision using NTP—and picks up new features at the same time. Check for and install updates with a single click directly via your clock’s web interface.
01
Connect
Pair with the Wi-Fi just once—right on the very first evening.
02
Check
The watch queries the Telltime update server and shows you via its web interface whether a new version is available.
03
Install
One click is all it takes. The update is first fully downloaded and verified, then activated—your settings remain intact.

Verified

Fail-safe
The update is first fully downloaded and verified, then activated. If the connection is interrupted, your watch continues to run unchanged.
