About this watch

The IWC IW5901-10 Portugieser Constant-Force Tourbillon Double Moon Platinum / Green is a masterpiece that marries technology with art. This stunning timepiece radiates elegance with its platinum case and green sunburst finish, making it an instant conversation starter. The 46 mm diameter case is bold yet refined, designed to fit comfortably on the wrist. The dial features Arabic numerals, feuille hands, and a mesmerizing combination of moonphase indicator and constant force mechanism display. At the heart of this watch is the IWC manufactured Caliber 94800, showcasing the brand's commitment to excellence with its 43 jewels and 18,000 vibrations per hour frequency. The patented constant force mechanism ensures stable amplitude, while the tourbillon escapement provides a unique 1-second jump. With a 96-hour power reserve, this watch offers reliability that few can match. Its 30 meters of water resistance means it can handle splashes and light rain, although it's not designed for underwater adventures. The limited edition of only 5 units adds a layer of exclusivity, making owning this piece a badge of honor for serious collectors.
