November 23, 1963
This Patek Philippe ad was published in the New Yorker Magazine on November 23, 1963 and it states:
Patek Philippe has left a deeper impression on the world of watchmaking than any other watch.

This ad features the really cool 18kK Patek Philippe Men's Perpetual Calendar, Minute Repeater Pocket Watch at the top, which is a Reference 844. The Reference 844 is also known as The American Digital Perpetual Calendar Pocketwatch.
This image appears courtesy of Antiquorum Auction House, and shows in better detail, the linear aperture which indicates month, date, and day of the week as well as the phases of the Moon. This is a super-clean, simple look for which Patek Philippe is renowned.
