The IWC Portugieser Perpetual Calendar 42 Ref. IW344207 combines the refined proportions of the Portugieser with IWC’s sophisticated perpetual calendar complication. Its 42.4 mm stainless steel case frames an elegant green dial paired with a matching green alligator leather strap, creating a distinctive and luxurious appearance. The dial displays the date, day, month, leap year and perpetual moon phase, while convex sapphire glass with antireflective coating on both sides provides clear protection. Central hacking seconds and the Pellaton automatic winding system further enhance the watch’s practical and mechanical character.

Powering the IW344207 is IWC-manufactured Calibre 82650, an automatic, self-winding movement operating at 28,800 vibrations per hour (4 Hz). The movement comprises 303 components and 46 jewels and delivers a 60-hour power reserve, with its refined finishing of Côtes de Genève and Perlage visible through the synthetic sapphire crystal case back. The 42.4 mm case measures 13.8 mm in height and offers 3 bar of water resistance. With its sophisticated green dial, stainless steel construction and highly capable perpetual calendar, the IW344207 is an elegant expression of IWC’s mechanical watchmaking expertise, with warranty coverage extendable to 8 years through the My IWC Care program.
