A gold pocket watch recovered from the body of one of the richest passengers on the Titanic is expected to fetch £1m at auction.

Isidor Straus and his wife Ida were among the more than 1,500 people who died when the vessel, travelling from Southampton to New York, sank after hitting an iceberg on 14 April 1912.

His body was recovered from the Atlantic days after the disaster and among his possessions was an 18 carat gold Jules Jurgensen pocket watch which will go up for auction on 22 November.

Auctioneer Andrew Aldridge, of Henry Aldridge & Son in Wiltshire, told BBC Radio Wiltshire: "With the watch, we are retelling Isidor's story. It's a phenomenal piece of memorabilia."

Mr Straus was a Bavarian-born American businessman, politician, and co-owner of Macy's department store in New York.
