Unless you've encrypted your phone, passwords and pattern unlocks only protect from casual attempts to break in. I see this in the same vein - sure, it's not going to protect you if someone steals both your watch and phone, but nor would pattern unlock, and nor would password unlock without the phone being encrypted.
