This 3970EG-016 is a fine example of an haute horlogerie complication which has become almost synonymous with Patek Philippe: the perpetual calendar chronograph. Highly collectable and coveted, it is considered by many as the pinnacle of Patek Philippe’s watchmaking and design prowess. As a member of this iconic lineage, the 3970 was created in the mid-80s, at a time when perpetual calendar chronographs were scarce. With it, a standard for all modern perpetual calendars was established. Timeless, elegant and discontinued - the reference 3970 is an investment for life, to be worn - and appreciated, daily.
