Since 1998, the Portugieser Chronograph has brought a touch of sporty elegance to the Portugieser collection from IWC Schaffhausen. The IWC-typical, vertical arrangement of the subdials displays the stopped minutes directly at the 12 o’clock position and places the small seconds at 6 o’clock. This layout enhances readability and has made the Portugieser Chronograph a design icon. Another feature is the inner flange printed with a quarter-second scale, enabling high-precision stop-time readings.
