Throwback Thursday: Patek Philippe Reference 3448 “Senza Luna”

To watch connoisseurs, the Patek Philippe reference 3448 needs no introduction. When launched in 1962, it became the world's first serially produced perpetual calendar powered by an automatic movement. It immediately also became one of the most beautiful, as even today, few other perpetual calendars can match the pure style of reference 3448. One of its most prominent features is the moon phase display, which is located at six o'clock, and surrounded by the dates, indicated by a hand. But not all reference 3448 have this feature, as some are "Senza Luna."
