Longines Observatory Chronometer Cal. 360

Post by koimaster » January 24th 2022, 10:20am

In the field of precision timekeeping, one inevitably encounters Longines with its multi-facetted and remarkably rich history.

The unwavering persistence of the firm’s celebrated régleurs and its long lineage of in-house chronometer calibres fostered Longines’ reputation for excellence in precision timekeeping, far beyond the borders of Switzerland.

The Saint Imier-based manufacturer ventured into precision chronometry as early as 1888, amidst the dawn of observatory chronometer competitions in Switzerland, when its cal. 21.59/60-based chronometer obtained an observatory-issued Bulletin de Marche, or rate certificate.

And after almost a century of steadfast participation in prestigious chronometry trials, the last Longines timepiece subject to observatory-governed testing, a cal. 262 based chronograph (movement no. 14’701’394), received its certificate in 1972.
