A Reinterpretation of the Timeless Portuguese Chronograph
The new Portuguese Chronograph Classic is slightly larger in diameter than the Portuguese Chronograph Ref. 3714 and 2 millimetres higher, although the latter makes little difference optically because of the arched-edge front glass. This traditional type of glass gives the design a classic balance that is enhanced by the railway-track-style chapter ring, which also gave the original Portuguese its distinctive appearance. The new Portuguese Chronograph Classic is equipped with the IWC-manufactured 89361 calibre. The movement was developed specially to show stopped times up to 12 hours on a separate subdial, which can be read off like the time of day.
