Patek Philippe

The Patek Philippe 5970 stands not only as one of the brand’s most iconic pieces but also as one of the most significant watches in modern horological history. The 5970’s origins trace back to the 1930s. Despite Patek Philippe’s already well-established reputation, the company—like most others—was not immune to the grave effects of the Great Depression. Saving the brand from potential demise was none other than the Stern family, particularly Philippe Stern.

Philippe Stern served as a long-time anchor for Patek Philippe, but with time, as often happens in family-run businesses, he saw it fit to hand over the reins. In 2009, his son Thierry Stern was inducted into the company’s leadership, with one of his first major undertakings being the launch of the 5970. Understanding that this transition marked the end of one era and the beginning of another, the younger Stern sought to bridge the gap between his father’s generation and his own—to create a timepiece that would capture the hearts of collectors both old and new.

The 5970 was the largest perpetual calendar chronograph ever produced by Patek Philippe at that time, significantly larger than the much-loved Ref. 3970, which measured 36mm in diameter. Thierry Stern explained that the increase in size was intended to improve legibility, which is certainly true, though it also coincided with a general trend toward larger watches across the industry. Despite the increase in case size, both models were powered by the same base chronograph caliber made by Lemania, the 2310, though heavily modified by Patek Philippe.

To ensure that the subsidiary dials did not appear ‘marooned’ in the center of the larger dial, a tachymeter scale was added beyond the railroad seconds track—not only to balance the proportions but also as a nod to the first and second series of the Ref. 2499. Similarly, the square pushers made a return in a clear homage to the reference’s lauded predecessors, the Ref. 1518 and first-series 2499. It is often said that the watch represents a perfect blend of vintage and modern design elements.

Produced in a single series between 2004 and 2011, it is estimated that only around 2,800 examples across all metals were ever made. The present lot housed in a yellow gold case and fitted with a silvered dial, is offered in overall very good condition.
