I didn't make that suggestion. My advice was to check your policy; the details vary a lot between insurers. With mine, anything under a certain value (I think £1500) is automatically covered. Above that you need to specify it on the policy. A £5K watch adds about £30 to the annual premium, which is fine. A small price to pay for peace of mind, really: if it wasn't insured, I would probably never wear it out of the house!
