writing 0 (zero) on Apple scribble for Norwegians
If you have trouble scribbling a 0 (zero) when asked to enter your Apple-ID password on your watch, turning the digital crown will offer you the options O, o and Ø. If you have english settings for your watch, the Ø stands for 0 (zero), not the Norwegian Ø... (not sure what happens when you have Norwegian languange for the watch, though...).
