The Timepiece

The perpetual calendar is IWC's signature complication — Kurt Klaus designed the original module in 1985 so the entire calendar sets from the crown. This 44mm rose gold Portugieser pairs the seven-day 52615 with a double moonphase at 12. Ardoise dial on black Santoni alligator — the flagship of the line.
