Apple Watch date complication error

Hi. This morning I noticed that my Apple Watch was showing the wrong date (yesterday's date). Tried changing the face, no result. Restarted, unpaired/paired with the iPhone, checked any possible calendar setting, no result.

Moreover, after the re-pairing the date is not showing at all, although if I choose the "events" from the calendar it displays them. Basically the complication is there, shows anything else but the date :))

Anyone had this issue?
