Notes

Patek Philippe dead independent seconds with two mounting barrels in series with uni-directional-winding and “free spring”

This watch is fitted with the new system with two mounting barrels in series with unidirectional-winding and “free” mainspring, which give will the Swiss invention patent No. 1 017, delivered to Patek Philippe, Geneva, on May 23, 1889, for a “Montre à secondes indépendantes à deux barillets se remontant ensemble par le même mécanisme de remontoir au pendant, et à deux corps de rouage dont le rouage des secondes est planté dans le même pont et au-dessus de celui de la montre.”.

In fact, this invention was already presented by Jean-Adrien Philippe (1815-1894), during the Universal Exhibition of Paris in 1867. This invention dates back to 1866. The Genevan manufacture will market watches of this type until 1913. As with its mechanism of winding and time-setting at the pendant, nearly a quarter of a century of reflections and improvements lead to the final version; that finally patented in 1889.

Very few of them were made; this watch is one of the first ten or fifteen produced according to this design.
