Although this pocket watch shares many features of a Chronometro Gondolo such as wolf’s tooth winding wheels, it was never exported to Gondolo & Labouriau, Rio de Janeiro. Between 1902 and 1930, Patek Philippe created an exclusive collection for the renowned Brazilian watchmaker Gondolo & Labouriau.
