Inside: Caliber CH 27-70 Q

Explore this caliber →

Based on a Nouvelle Lemania ebauche, the CH 27-70 Q powered the iconic references 3970 and 5970. With added rattrapante function (CHR 27-70 Q) it also served in the much-coveted 5004. It was the last of the Patek Philippe Perpetual Calendar Chronograph movements not to be fully in-house.

33 other watches in the library run the Patek Philippe CH 27-70 Q.
