Catalogue Note

In the unprecedented series of Patek Philippe ‘Grande Complication’ models featuring a perpetual calendar chronograph and moon phases, reference 3970 replaced, after 50 years, the acclaimed reference 2499 as of 1986. It was characterised mainly by the new ‘Lemania’ based movement. It was initially fitted with a solid snap-on (hyphen added) case back however soon followed by a solid screw back, which made it waterproof. The model was to be referenced 3970E (‘E’ referring to the french word ‘étanche’ – meaning waterproof). Subsequently, a model with a sapphire screw back was launched, reference 3971E. This corresponds to the present model, and can be counted among the most important pieces for significant collector’s wristwatches.
