Of historical, and horological importance, this is 1 of 662 pieces released after the last year of the Observatory Trials held at Neuchatel that ended for the wristwatch category in 1967. The competitions ran at Neuchatel from 1945 to 1967.

This was a ‘last hurrah’ and a grand effort by Girard Perregaux before the incoming tidal wave of Quartz, and subsequently changed watchmaking forever.

Out of all the watch companies who submitted movements to the Observatory Competitions, only Seiko and Girard Perregaux cased and sold their ‘competition chronometers’ commercially. These movements were specially prepared for the competitions (like an engine prepared for Formula 1, and not a street-legal car), each to be rigorously tested for a consecutive 45 days. These would have not been intended for the wrist.

The Calibre 32A was the world’s first serially produced Hi-Beat movement, running at 36,000pbh. An extremely fine and highly engineered movement with 39-jewels.

Dial & Glass: This particular watch possesses a fine, vertically brushed finish in solid gold. It is completely original including the glass, with its rectangular cyclops.

Case: A dense gold case in a ‘squared’ design, manufactured by the casemaker ‘Serva S.A.’ based in Grenchen, with the ‘Ponçoin de Maître’ of ‘352’. An extremely rare case, and not before seen with any GP Observatory Chronometer. 34mm. (They are most often seen in ‘C-shaped’ cases, with fluted bezels).

Crown: Original and signed ‘GP’.

Movement: Famed Cal. 32A. Freshly serviced in the last 3 months, and is running very well. The first serially produced hi-beat movement, running at 36,000bph, or 5hz.

Pedigree: The Calibre serial number bears ‘15646’, regulated by P.Nicolet, La Chaux-de-fonds, and had competed in 1967. Information provided by Dr C. Mueller, curator of the Observatory Chronometer Database, at
