The two most import catalysts for the development of aviation watches were early aviation record attempts and war. World War I finds watch development between the pocket watch and the new wristlets with the British issuing pilots pocket watches. British Mark IV.A and Mark V pocket watches are an example of WW1 military aviation innovation. Mark V (1916) pocket watches were standard issue to British Royal Flying Corps & Royal Navy Air Service piolts. The RFC and RNAS had near identical watches, but the RNAS watches were predominately the eight-day variety and the RFC, the 30-hour. Once inside the aircraft, these watches became chronometric instruments, which the pilot fit into the instrument panel. As a result, the Mark IV.A and Mark V had long shank winding stems to extend beyond their instrument panel housing for mid-flight winding, earning the nickname, cockpit watch. The RFC aviation issue watches had an underscored capital A with a broad arrow pointing upward underneath it. This is a very rare original, WW1 British MK V RFC cockpit watch by the quality Swiss manufacturer Omega. The watch has all of the correct MK V features and dial markings (illustrated) . The case cover has the correct Air Ministry ‘A with Broad Arrow mark and other numbers (illustrated). The watch is in fully working order.
