In the 1960s, Patek Philippe sold, in very limited☂ quantities, a celebrated group of what would go on to be known as the 'Modern' pocket🎃 watches. From the vaults of the great maison, a number of complicated movements from the early 20th century were discovered and, in a stroke of genius, housed in cases radically different from those produced contemporary to the movements.

Instead, the cases featured bold lines, from their dauphine hands to their stepped bezels. The cases were designed by Antoine Gerlach: interestingly, the same casemaker as f꧅or the famed Ref. 3448. Indeed, the similarities between this series of pocket watches and the architectural vintage wristwatch are distinctly apparent. The sharp edges at every turn were then, and continue to be, a welcome shift from the more conservative 'bassine' form cases most typically associated with the pocket watch format. Today, collectors who typically seek vintage wristwatches by the firm take special note of this category: it is a pocket watch for the pocket watch collector, but in a novel twist, also perfectly befitting a wristwatch collector. 

From the 'Modern' pocket watch genre, there are so far about 20 references known, most understood to exist only in one or two examples. Ref. 767 is, interestingly, a reference that represents the transition into the 'Modern' category. Of the 7 known examples, each piece has a different case and dial, and they are distinguished by the suffix to the reference number (/1, /2, /3). Some resemble more classic earlier pocket watches, and some, like the present, carry the attributes of the 'Modern' pocket watches. The known examples from this reference are unified in their shared complications. According to our resear𓆉ch, the present lot is the only Ref. 767/3 known to exist.
