In Switzerland, a long tradition of chronometric certification dates back to the creation of the Geneva Observatory (Observatoire de Genève) in 1772, which held its own chronometric competition from 1872 to 1968. The role of the Geneva Observatory consisted of assessing and rating Swiss timepiece movements for accuracy. Movements that passed the stringent tests were issued a certification from the observatory called a Bulletin de Marche, signed by the Directeur of the Observatory. The Bulletin de Marche stated the testing criteria, and the actual performance of the movement. A movement with a Bulletin de Marche from an observatory became known as an Observatory Chronometer, and such were issued a chronometer reference number by the Observatory.

The movement of the present Vacheron Constantin pocket watch is dated 1945. This chronometer reference number is VC 464268. This chronometer participated 19 times in the competitions of the Geneva Observatory, from 1948 to the last competition held in 1968.

In the last competition in 1968, chronometer VC 464268 was awarded 53.28 points out of a possible total of 60 points. The winner of the competition obtained 55.08 points while the chronometer which ranked last obtained 47.37 points. Chronometer VC 464268 ranked 7th place out of 15.

With its prestigious history of awards from the Geneva Observatory, the movement of this present pocket watch represents the finest expression of Swiss horological traditions.
