Inability to Upgrade to Watchos 7.0.1

I'm on an apple watch, series 3, watchos 7.0 (18R382). Can't update to version 7.0.1. Having this inability since release date. The update is normally (and fully) downloaded to the watch. However, in the end, it pops up a message saying "it wasn't possible to verify the update", then "the watchos update couldn't be verified because there is no connected to the internet" [translated the message for it's on portuguese]. Don't understand that, because the update is fully downloaded (so there has to be a internet connection active), my iPhone is obviously connected (even tried with diferente Wi-Fi) and so is me watch (also tried with different Wi-Fis). PS.: tried turning on and off several times, even formatted (with backup then)
