Longines were the official timers from the 1952 Olympics in Olso to the 1980 games in Moscow, including summer and winter events, plus many, many other events in the sporting calendar, after developing large 24 lines chronometer calibers. They were later modified to become cal. 260 in 1957, and then cal. 262 in 1966, such as the present watch. They were even sent to the Swiss Observatory for timing at Neuchatel. They were Longines’s pinacle instruments for professional timing. They were kept by the factory and lent out for all types of events from Olympic games, to the timing of Donald Campbells “ Bluebird “ water and land speed record attempts ( and everything in between ), according to scholars.
