Catalogue Note

As the direct successor of reference 2499 (see lot 134 and 245), reference 3970 launched in 1986 and remained in production until 2004.  Manufactured in yellow gold, white gold, rose gold and platinum, reference 3970 was considered a standout from prior perpetual calendar chronographs produced by the firm. Some of the most noteworthy modifications were made to the size and the movement. 

The movement in previous perpetual calendar chronographs, such as references 1518 and 2499, were Valjoux based movements, whereas reference 3970 was the first Lemania based movement used in a chronograph - caliber CH 27-70 Q. The slightly smaller movement allowed Patek Philippe to create a smaller case size, measuring to 36 mm diameter.

The 'E' in reference 3970EJ stands for étanche, french for waterproof - referring to both the solid and sapphire screw-down casebacks the watch can be fitted with. The present example is in superb condition, and an excellent addition to a growing watch collection.
