This limited edition flight instrument was inspired by the 4e RHFS, the French special forces helicopter battalion. In the flight instrument style of the Oris BC4 collection, the case is coated in gunmetal PVD – an allusion to its military origins. The background of the small second carries the French military logo and the tip of the second hand features the French tricolore. Limited to just 1000 pieces it’s an all-action pilot’s chronograph.
