Launched in 1993 and produced until 2002, reference 5050—alongside its officer-style sibling, reference 5059—remains one of the most underappreciated models of modern Patek Philippe watchmaking. For the first time in the brand’s history, a perpetual calendar was paired with both an automatic movement and central seconds—bringing together two hallmark features of revered vintage references: 3448/3450 (automatic) and 2497/2438-1 (center seconds).

Adding further distinction, the 5050 features a retrograde date display, introducing a dial layout rarely seen on Patek Philippe timepieces, and until then, unprecedented in regular production models. The present example is particularly appealing as an early production model, dating to the year 2000, and was originally sold through the prestigious Swiss retailer, Gübelin.

Produced in all three gold variants as well as platinum, the model also underwent subtle dial evolution during its run. The earliest examples were fitted with railway minute tracks and Roman numerals—a design soon phased out. In parallel, the baton index configuration seen here was also introduced, offering a cleaner, more modern aesthetic.

Offered as a full set with all of its original accessories, this example presents a rare and compelling opportunity for the collector—an under-the-radar masterpiece with both technical innovation and timeless style.
