Consigned by a private collector this watch has never been offered in public before. It is one of the few small size pendant watches made for the Brazilian firm Gondolo & Labouriau, Patek Philippe's sole retailer in Rio de Janeiro as early as 1872. The enormous success of Patek Philippe watches among the firm's clients in Brazil lead to the production of timepieces especially for Gondolo & Laboriau, starting in 1902 with the registration of the trade name "Chronometro Gondolo" in Switzerland until the 1930s. During this collaboration lasting over a quarter century, the Brazilian retailer sold nearly a third of Patek Philippe's total production.

Various examples of "Chronometro Gondolo" pocket and wristwatches are illustrated and described in Patek Philippe Museum - Patek Philippe Watches - Volume II, pp. 120 - 139
