This fine example of a Patek Philippe precision lever chronometer was made for participation in Observatory timekeeping contests. Such movements were, like the present watch, engraved with the movement number twice. The inscription "Extra" on the bridge of the movement refers to the very high finishing of all the parts of the movement. Constructed using a LeCoultre & Cie and Victorin Piguet & Cie. ébauche. The centre wheel has a jewel in a gold chaton, the escapement is a counterpoised straight line lever and the balance spring has terminal curve. This watch achieved chronometer standard as attested to by the stamping of the movement with the Seal of Geneva (twice).
The very attractive silver dial bearing the movement number is distinguished by the applied gold Roman numerals. It is believed to be the so far only example of such watch found with this configuration. Fully confirmed by the Extract from the Archives, it gives the watch a strong and individual character.
Precision timekeeping has always been vital to the scientific community, and in 1873, the first annual chronometer competition was held at the Geneva Astronomical Observatory. Rigorous quantitative internationally recognized testing standards were established. The testing, which initially lasted for 40 days, consisted of placing the watches in various positions and temperature conditions. Patek Philippe were awarded a First Prize in the competition as early as 1884.
An Observatory tested chronometer with identical ébauche to the present watch is illustrated in: Patek Philippe Watches, Volume II, Patek Philippe Museum, p.32.
