The pocket watches in the selection include a watchmaker’s personal watch — Patek Philippe co-founder Jean-Adrien Philippe’s piece featuring the company’s signature and independent seconds movement, patented and manufacture in 1889. The Genevan watch has an enamel dial with Roman numerals. Another pocket watch by the same firm had been presented to Pope Pius IX by the Swiss Catholics on the occasion of his episcopal golden jubilee in 1877, and so the Pope’s coat of arms is engraved on its silver body.
A vintage Patek Philippe watch from 1977 (reference 2499), with a perpetual calendar mechanism, is estimated to be among the highest earners, likely to bring in some 500,000 Swiss francs ($498,000). It is notable for featuring in the company’s collection for 35 long years, during which only 349 pieces were made, that is about 10 watches each year. Aside from antique watches are a few modern examples sourced from private collections, among them a piece styled from titanium by Swiss luxury watch brand Richard Mille named after football manager Roberto Mancini, and a carbon-based watch named Rafael Nadal.
