An updated version of the Portuguese Chorograph Classic, this model features a larger dial and 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. The new Portuguese Chronograph is equipped with IWC-manufactured 89361-calibre movement. This movement was developed specially to show stopped times up to 12 hours on a separate subdial, which can read off like the time of day. The polished stainless steel case features a silver-plated dial and black Santoni strap crafted of alligator leather for an ergonomic and comfortable fit.
