Just bought new second hand watch and trying to connect to existing account.
How to do this.
Do a factory rest, which will take you through the registration process. When it asks you for your email to set up an account, use your existing account's email and will register it to that account.
I hope this helps answer your question. If so, please mark it as a solution so others can look for it if they have the same question.
