Movement

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.

Description

The Patek Philippe reference 3971 is a rare variation of the 3970, exclusively fitted with a glazed screw back. Most were fitted with a silver dial. The pictured example however, a 1989 model later to appear in a Christie's auction, features a rare gilt dial.
