Description
Longines developed a caliber specifically intended for observatory competitions: the 360. The generous size of the rectangular
movement houses a large barrel spring and enables the use of a wide sprung balance, oscillating at a frequency of 36,000 vibrations per hour,
for even greater accuracy. The 360 calibre has set new records for accuracy in the wristwatch category at the Neuchâtel Observatory.
An extremely rare, legendary competition chronometer from the 1st series in an aluminium block case. The caliber 360 is a very rare observatory
calibre especially made for competition trials, about 200 were made in 4 series. This piece from the first series, 1959.
Silvered dial marked “Longines chronometer” with baton hands and numbers and subsecond dial with photo indexing.
This watch participated 5 times in Neuchâtel (1959, 1960, 1964, 1964 and 1965) and won 5 First Prizes.
