Notes

It should be noted, however, that the production sheets of the watch No. 11 167 are unfortunately no longer present in the Historical Archives of the Louis Audemars house, now kept by Mr. Paul Audemars in England.
 At the time of its creation, this type of watch with horological complications represents the pinnacle of production because it’s only circa 1873- 1875 that we will build watches with minute-repeater and chronograph. The Louis Audemars house in Le Brassus (Vallée de Joux), founded in 1811 by Louis-Benjamin Audemars (1782-1833), is one of the specialists. 
Only, are even more complicated the pieces made on an exceptional basis, as those built for the industrial, national or universal exhibitions by this house which also supplies its colleagues: Breguet, Oudin and Le Roy (who will become L. Leroy & Co.) in Paris; Patek Philippe and Vacheron Constantin in Geneva; etc.
 Later, other exceptional watchmakers from the Vallée de Joux are also specialized in this type of production: Louis-Elisée Piguet (1836-1924), Ami LeCoultre (1843-1921), Léon-Ernest Aubert (1845-1921) 1920), Victorin Piguet (1850-1937), etc.
