Unworn IWC Portugieser Tourbillon Mystere Automatic, 18k Rose Gold, 44.2mm, Ref# IW504202, box and papers

The unworn IWC Portuguese Tourbillon Mystère Ref. IW504202 is a masterclass in horological artistry and timeless sophistication. Crafted from brushed and polished 18k Rose Gold, its commanding 44.2mm round case with a 14.2mm profile exudes presence without sacrificing elegance. The silver dial is a study in refined design, featuring polished 18k Rose Gold hands, bold Arabic numerals, and a precise minute track along the outer rim. At 12 o’clock, the highlight of this masterpiece reveals itself—the captivating “Mystery Tourbillon.” This one-minute flying tourbillon appears to rotate freely in space, without visible attachment or axle, an illusion that fascinates even the most seasoned collectors. Balanced against this visual spectacle, the small seconds sub-dial rests at 9 o’clock, while the power reserve indicator is positioned at the lower right, subtly reminding the wearer of the watch’s extraordinary 168-hour autonomy. This remarkable endurance comes from the in-house IWC Calibre 50900, a meticulously engineered movement with 44 jewels, visible through the transparent case back. A smooth 18k Rose Gold bezel frames the dial, protected by a domed, scratch-resistant sapphire crystal with anti-reflective coating on both sides. Completing the ensemble is a rich brown leather strap paired with an 18k Rose Gold folding clasp. Water-resistant to 30 meters, the Portuguese Tourbillon Mystère is not just a watch—it’s a statement of mechanical poetry and refined taste.
