Patek Philippe introduced their first perpetual chronograph wristwatch, the reference 1518, in 1941, and it is considered an important milestone wristwatch in horological history. Its timeless aesthetic was the foundation for a long line of successful and highly sought after complicated wristwatches, including the references 2499, 3970, and like the present watch the reference 5970.

Reference 5970 has a similar design and dial layout to its famous predecessors with day and month indicated via apertures, the date and moonphase display elegantly poised at 6 o’clock. Launched in 2004 and in production for only 7 years, the reference 5970 had the shortest run for any perpetual calendar chronograph by Patek Philippe. Discontinued in 2010, it was replaced by the current reference 5270 based on Patek Philippe’s first in-house chronograph caliber. Reference 5970 relied on a heavily modified Lemania base caliber, housed within a well-proportioned, 40mm case with facetted lugs. The model became an instant success, and since its discontinuation, it has only increased in popularity and collectability.

Offered in outstanding condition and complete with its Certificate of Origin and additional solid caseback, the present pink gold example is a rare opportunity to own one of these exceptional perpetual calendar chronograph models.
