Accompanied by Patek Philippe Extract from the Archives confirming production of the movement in 1893, casing in 1913 and its subsequent sale on 24 January 1914.
It is thought that the present watch with its 6 lignes movement is the third smallest watch and possibly the smallest with a lever movement ever made by Patek Philippe.
The company's smallest but keywound watch with a diameter of only 9.023 mm. or 4 lignes movement was exhibited at the London World Exhibition in 1851 (see Patek Philippe Pocketwatches by M. Huber & A. Banbery, p. 106, pl. 13). The second smallest example features a keyless 5 lignes cylinder movement manufactured in 1893 and numbered 97'332.
