Thank you for using the W770 watch.
We decided to change specifications related with the “Light Level” function partially, which gives you graphic indication of power generation amount of the watch, as users of data-backup service of power generation amount have declined.
We will carry on update of the dedicated app according to the change of the specifications.
After the update, past data of power generation amount are removed when you change your smartphone or remove the app.
We are very sorry for inconvenience and thank you in advance for your understanding.

Thank you for using the W770 watch.
As we noticed on June 8, 2023, on the dedicated app, settings for the filtering function of X (former Twitter) have been unavailable.
This time we decided to change specifications and remove the filtering function on the dedicated app.
By executing notification settings on the X official app, you will be able to get equivalent result as the filtering function gave you.
We are very sorry for inconvenience and thank you in advance for your understanding.
