25720BA, Star Wheel, Yellow Gold UR-100V P.02 A Tank Louis NSO withA ref. 25720BA Star Wheel with a guilloch dial. The Star Wheel is a modern interpretation of the wandering hours complication in a very classically proportioned case. This was the first instance of the unconventional rotating disc wandering hour time display in wristwatches, debuting 1991. Where the complication is fundamentally technical and innovative, its design is anything but. That classicism and paradox is what defines the original Star Wheel.
