Most insurers are used to getting claims for Rolex watches, whether genuine or not.

But MMA had no trouble foiling a recent fraudulent claim for one of the timepieces.

A crooked customer put in a £4,000 claim for a Rolex and was happy to oblige when the insurer asked for evidence that he had owned one.

The man provided a photo of himself in his office with his shirt sleeves rolled up to show off the flash watch.

So far, so good. His only mistake was to overlook the fact that behind him was a calendar, with the days crossed off, showing the date to be two weeks after he had first made the claim.

He later withdrew it.
