About this watch

The IWC IW5901-02 Portugieser Constant-Force Tourbillon Double Moon Platinum / Ardoise is a masterpiece of horology that embodies the essence of fine watchmaking. Crafted from platinum, this limited edition piece features an elegant design and precision mechanics. The sunburst grey dial adds depth and catches the light beautifully, while the feuille hands are elegantly designed to complement the overall aesthetic. At its heart lies the IWC caliber 94800, a hand-wound movement with patented constant force mechanism and tourbillon escapement. This watch boasts an impressive 96-hour power reserve and double moonphase display, making it a conversation starter that adds another layer of functionality to keep track of time in both light and dark. With its water resistance of 30 meters, it's suitable for everyday wear, though it's advisable to keep it away from deep-water activities.
