Description
The Patek Philippe 3970E was introduced around 1992 as the third series of the 3970, with the 'E' signifying 'Etanche', French for waterproof. This series was delivered with both a closed as well as a see-through case back.
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.
