This pre-owned IWC Portuguese Perpetual Calendar, reference IW502119, is a 44.2mm 18k rose gold dress watch produced between 2005 and 2012, and belongs to IWC’s Portuguese (Portugieser) collection — a line with roots tracing back to the late 1930s, when two Portuguese businessmen commissioned IWC to build a precision marine chronometer in wristwatch form. That brief resulted in an oversized case with a clean, legible dial, later paired with IWC’s celebrated Kurt Klaus-developed perpetual calendar module to create the Portuguese Perpetual Calendar line. The IW502119 is the rose gold, black-dial execution of that formula, produced as a standard catalogue reference before being succeeded by later generations.
The black dial is fitted with applied rose gold Arabic numeral hour markers and rose gold Dauphine hands, framing a full suite of perpetual calendar sub-dials: a day and small seconds register at 9 o’clock, a month indicator at 6 o’clock, a four-digit year aperture between 7 and 8 o’clock, and a double moonphase display for both hemispheres at 12 o’clock. A date and 7-day power reserve indicator sits at 3 o’clock. The watch is powered by the IWC-manufactured Calibre 51613, an automatic movement with the brand’s patented Pellaton winding system, 62 jewels, and a 168-hour power reserve, with the calendar mechanism automatically adjusting for varying month lengths and leap years without correction. The case is fitted with a scratch-resistant sapphire crystal, a screw-down sapphire display back secured by six screws, and is water resistant to 30 metres, completed with a black alligator leather strap and 18k rose gold deployment buckle.
Pre-owned examples of this reference currently trade from around $16,600 USD for watch-only pieces up to $25,200 USD for full-set examples with box and papers — making this a comparatively accessible way into IWC’s flagship perpetual calendar complication in solid gold, well below current retail on the modern-generation equivalent. This pre-owned IWC Portuguese Perpetual Calendar has been authenticated, tested, regulated, and pressure sealed by Topwatch’s watchmakers, and is sold with a 12-month Topwatch warranty.
