Rheinhard Meis notes in his book, Das Tourbillon (1986, p.350) that the movement of this watch was submitted to the Neuchâtel Observatory contests in 1871. It is understood that Henri Matthey-Peytieu of Le Locle was the firm of Henri Théophile Matthey-Henry (1817-1893) who incorporated his wife's name of 'Peytieu' into that of his company (see: K. Pritchard, Swiss Timepiece Makers 1775-1975, Vol.II, p.M-33).
