IWC Portugieser Portugieser Constant-Force Tourbillon Double Moon Red Gold / Silver

Reference IW5901-08

About this watch

The IWC Portugieser Constant-Force Tourbillon Double Moon IW5901-08 is a masterpiece of horological excellence. Its luxurious red gold case and stunning silver sunburst dial make a statement. The round shape and 46 mm diameter provide a bold presence on the wrist, balancing elegance and masculinity. The hand-wound IWC caliber 94800 showcases IWC's engineering prowess with its integrated constant force mechanism and mesmerizing 1-second jumps of the tourbillon. This exceptional timepiece performs with consistency, even as the power reserve dwindles. With a 96-hour power reserve, thoughtful features like the power reserve indicator ensure you're never caught off guard by a stopped watch. The double moonphase display is where this watch really shines, showing the current phase of the moon and its position in relation to the other celestial body. It's an astrological companion that invites conversation and wonder.
