Portugieser Perpetual Calendar : IW502307

The IWC Portugieser Perpetual Calendar IW502307, released in 2010, is a distinguished member of the prestigious Portugieser collection. This model showcases a refined 44.2 mm white gold case and features a transparent caseback, which offers a glimpse into the intricate workings of its self-winding 7-day movement. The ardoise-colored dial is complemented by the 'Single Moon' moonphase display, providing an elegant and functional readout of the moon's phase in its respective hemisphere. The perpetual calendar module, developed by Kurt Klaus, traces its origins back to the 1985 Da Vinci model and has been expertly adapted for integration with the larger dimensions of this timepiece’s movement. Sapphire crystal glasses protect both the front and back of the watch, ensuring durability while maintaining clarity. The overall style is sophisticated, balancing modern engineering with classic aesthetic elements characteristic of IWC's horological craftsmanship.
