The 14-carat gold Waltham pocket watch, engraved “JJA”, was found when Astor’s body was recovered from the Atlantic Ocean seven days after the sinking of the liner. Astor was reputedly the richest man onboard the ship and a prominent member of the Astor family. The watch is tipped to fetch between £100,000 and £150,000 at auction in Devizes, Wiltshire, on Saturday.
