Our remarks

We are very proud to offer you this excellent PATEK PHILIPPE Perpetual Calendar Chronograph Moon-Phase Ref.3971 in 18k yellow gold with croco leather strap and 18k PP buckle.

Coming with the original box, Patek leather etui, description booklet and a letter from the PATEK Archive - 1987.


This is super rare 3971 has got a SNAP sapphire back. This early watch model was manufactured only for a very short time and was soon replaced by the 3970 with a screw down back. Only very few pieces were delivered with this option.

This is a high-end collectors grand complication and of course a great investment piece.


THE legendary PATEK complication (perpetual calendar with chronograph) since the late 1940s with the first sapphire back.


1 year warranty through our watch lab.


- We buy watches since 1991. -
