We’ve recently found out a critical vulnerability of the battery monitoring of the Witty Timer that may cause problems with revealing the correct battery charging status.
To solve this hardware low-level problem, it is necessary not only to upgrade the firmware but also to upgrade part of the operating system and of the “boot loader”. To do this it is necessary to follow some more steps than for a normal firmware update
The procedure is fully explained at the following link:

We recommend you to update your chronometer(s).
We apologize for the inconvenience but we are glad to have avoided any physical recall of the devices.
For any questions or problems, feel free to contact us.
