The perpetual calendar chronograph is a technical masterpiece of Patek Philippe and represents the pinnacle of its manufacturing philosophy. With the 1518 and 2499 now virtually unattainable, the 3970 remains a readily available model with a relatively high production volume.
Following the luxury sports watch boom, and with the recent shift towards smaller sizes, many mechanical watch collectors are likely thinking, ”(Following the 5970, which saw a significant upgrade a few years ago) I should acquire the 3970, which has remained reasonably priced, while I still can."
Certainly, watches with in-house movements can be produced in additional quantities, but those with Lemania movements cannot. Furthermore, the 3970, with its push-button adjustment of various indicators, is a very user-friendly model, even if not something we typically wear daily.
Above all, the dial’s perfection (balance) is outstanding. The early models, especially those with leaf hands and rectangular indices, will undoubtedly continue to captivate many watch enthusiasts.
