PATEK PHILIPPE YELLOW GOLD SELF-WINDING CALATRAVA

The ref. 3998 was launched in 1989 and remained a staple offering in the Patek Philippe collection until being discontinued in 2007. With a water resistant, screw-back, 33 mm diameter case and an attractive date dial layout with sweep seconds, this watch was a commercial success and remains highly desirable to this day.

This example is from the rare first series of the reference’s execution with a caliber 310 SC which was used from 1989 until 1993. Later examples feature the caliber 315 SC. It is beautifully preserved and ready to wear.
