The IWC Portugieser Yacht Club Perpetual Calendar 42 Ref. IW344101 brings together the sporty character of the Portugieser Yacht Club with IWC’s renowned perpetual calendar, originally conceived by Kurt Klaus. Its 42.4 mm case is crafted from 18-carat Armor Gold® and paired with a sophisticated black dial and black rubber strap. The dial presents a comprehensive perpetual calendar displaying 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 a screwed-in crown add practical functionality to the refined design.

Inside, the timepiece is powered by IWC-manufactured Calibre 82651, an automatic, self-winding movement featuring the Pellaton automatic winding system. Operating at 28,800 vibrations per hour (4 Hz), the movement comprises 307 components and 46 jewels and provides a 60-hour power reserve. The 42.4 mm case measures 14.1 mm in height and offers 10 bar of water resistance, while the synthetic sapphire crystal case back provides a view of the finely engineered movement. Combining precious 18-carat Armor Gold®, advanced perpetual calendar functionality and a sporty nautical aesthetic, the IW344101 is a distinctive luxury timepiece designed for discerning watch enthusiasts.
