In the year 1872 Patek Philippe delivered a silver pocket watch to the Brazilian firm of Gondolo & Labouriau. Thus began a collaboration between the two firms that would last until 1927. In 1902 the owners of the Rio de Janeiro based Gondolo & Labouriau (Carlos Gondolo & Paulo Labouriau) commissioned Patek Philippe to create a watch exclusively for their firm. The result was a very high quality calibre called ‘Chronometro Gondolo’. Its specifications required the ebauche to be based on Adrien Philippe’s patented design (US patent No. 20483 of Jan 13, 1891), the train to be of 9 carat gold and the escapement to be straight line ‘moustache’ lever with cut bimetallic compensation balance. The movement was also required to have a Breguet balance spring, a minimum of 18 jewels and to incorporate François Wilmot’s patented micrometric cam regulator (US patent No 129197 registered on July 16, 1872).
