Description
IWC has been a pioneer of perpetual calendar watchmaking since Kurt Klaus developed the brand’s legendary movement in the 1980s. This Portugieser is a beautiful and complicated version with a midnight blue dial that displays a beautiful perpetual calendar laid out across four subdials at 12, 3, 6, and 9 o’clock. Along with the day, date, and month layout, there is also an indicator for the 8-day power reserve, a year display, and a moonphase. The sapphire crystal on this watch is domed and creates a satisfying viewing experience of this exceptional dial.
