This Longines was a pinnacle instrument. Sent to the Swiss Observatory at Neuchatel for timing and kept by the factory, they where used for all types of important events from Olympic games to the timing of Donald Campbell’s Bluebird water and land speed record attempts.

Developed from the early cal. 24 from 1939, modified to 260 in 1957 and finally to 262 in 1966 with hours, minutes, seconds & 1/10 second split-second chronograph with 30 minutes counter.
