May already have been posted but for all watches, even those worth just a few hundred pounds try to keep the box the watch arrived in, as well as any documents.
Failing that ensure you take images of any valuables you have, especially taking note of the serial number of a watch as they're registered on various databases.
My Dad had an 1850's fob watch which was valued at £800 when his house was broken into around 40 years ago, he kept it in his drinks cabinet in the bottom of a Whisky box but the robbers found it. When he claimed on his insurance they paid him £200. All a bit different now but the more evidence you have of owning valuable items the better chance you get of being paid the correct amount of the claim.
Also for items like iPads/laptops/expensive TV's keep and photograph the user manual as well as receipts, they're accepted as proof of ownership by Insurance companies.
