Released in 2004, the Patek Philippe reference 5970 had one of the shortest production runs for the company, lasting approximately 6 years from 2004 to 2011. This reference was the last perpetual calendar chronograph model to use the revered, Lemania 2310-based movement.

Proud heir to Patek Philippe's prestigious perpetual calendar chronographs starting with reference 1518, 2499, and 3970, the reference 5970 was the first model developed and designed by Thierry Stern upon his accession as President of the company. The reference 5970 in white gold, like the present example, alongside the pink gold version, was the first variant introduced in 2004 and remained in production until 2009.

The design of the 5970 takes cues from the past but interprets them in a thoroughly modern way. Forty millimeters in diameter with faceted lugs, it was a notable increase in size from its immediate predecessor, the reference 3970. It is noteworthy that the larger case does not jeopardize the symmetry and comfort of the watch at all; on the contrary, the watch is extremely wearable and retains a very balanced symmetry.

The tachymeter scale encircles the day and month windows, which themselves are clear and legible. The three subdials are also perfectly aligned and in symmetry with the outer dial as well as with the minutes, hours, and chronograph hands.
