Then they came across a stall specialising in aeroplane memorabilia. They found a compass that was taken from an aeroplane cockpit. It had a round dial set in a square case which was secured to the cockpit facia by four screws set in the corners of the compass case. This is the look that has become iconic as the case style predominant in watches made by the French watch company Bell & Ross. Worth has a Bell & Ross with this particular styling. He was over the moon with this find.
