Owned Jewellery and Airport Customs

[Blown2CV]

If I was to wear a watch I already own on holiday, what do i need to do to ensure I don't get potentially pulled up at customs on return to UK? Some chat on another thread seemed to suggest that it's just chance whether you get pulled up, and unless you can prove ownership there and then, they can take it off you jut in case you might be trying to import it and skip paying duty! Could be scaremongering, but if you're just wearing a watch then is this really a risk??
