Important notice: Whilst many home insurance policies may cover certain pieces of jewellery or watches we would advise all customers to check their policies closely. Certain household policies have restrictions on watch and jewellery cover, and may include limitations such as, no accidental damage cover, no cover outside of the home or cover for holidays abroad. They may also restrict your choice of jeweller for repair or replacement. In the event of a household insurance claim, you may be expected to pay an policy excess and any claims made may affect your future premiums.
