IWC Portuguese Yacht Club Chronograph

About this reference

The IWC Portuguese Yacht Club Chronograph reference IW390204 was produced between approximately 2010 and 2014 as part of the first generation of the modern Yacht Club line. Collectors focus on this reference for its integration of the in-house Calibre 89360, which features a flyback function and a unique totalizer at 12 o’clock that displays both elapsed hours and minutes on a single sub-dial. The 45.4mm stainless steel case includes a screw-down crown and 60-meter water resistance, distinguishing it from the standard Portugieser line. This specific reference is characterized by its black dial with red accents and a rubber strap. On the secondary market, the IW390204 typically trades between $6,000 and $8,500 depending on condition and the presence of original documentation. While the 3902 series was later replaced by the smaller 43.5mm IW3905, the IW390204 remains noted for its larger case proportions.
