Patek Philippe

Reference 3971

Year 1989

Caliber CH 27-20 Q

Full Set

This 1989 yellow gold Patek Philippe Ref. 3971 represents one of the pinnacle of Patek Philippe’s haute horlogerie in the post-classical period. A direct evolution of the legendary 2499, this perpetual calendar and moon phase chronograph combines technical rigor and aesthetic refinement in a perfectly proportioned 36mm case.

The yellow gold version, the rarest of the variations, is estimated to have been produced in approximately 170 pieces, making it one of the most sought-after references among collectors today. The silvered dial with slightly recessed subdials offers impeccable readability and masterful visual balance: a two-counter chronograph with a 24-hour display, a complete perpetual calendar, and a perfectly integrated moon phase display.

Inside, the renowned CH 27-70 Q caliber beats, a manually wound movement finished to the highest Geneva standards, considered one of the most iconic movements ever created by the manufacture.

Offered as a Full Set, this piece retains not only exceptional collectible value but also a unique historical aura: a transitional timepiece, an ideal bridge between the artisanal traditions of the past and Patek Philippe’s modern vision.
