Pre-owned IWC Portugieser Perpetual Calendar ref. IW503406 (2025) pairs one of IWC's most impressive complications with the classic, elegant design of the Portugieser. Introduced in 2018, this impressive model features a large 44.2mm platinum case paired with a silver dial, creating an understated monochromatic backdrop for a surprisingly complex display. The perpetual calendar tracks the date, day, month, and year, including a four-digit year window positioned near 6 o'clock. Four registers organize all that information beautifully: the power reserve at 3 o'clock is surrounded by the date, the month sits at 6, and small seconds at 9 is paired with the day of the week. At 12 o'clock, IWC's distinctive double moon phase simultaneously displays the lunar cycle for the northern and southern hemispheres. Inside is a self-winding movement with an impressive seven-day power reserve and an 18k 5N gold rotor, visible through the sapphire caseback.
