IWC Portugieser Tourbillon F.A. Jones Platinum Black Dial SIGNED LIMITED

The IWC Portugieser Tourbillon F.A. Jones ref. IW544704 combines a black dial with a platinum case, giving this version of the Portugieser a formal, high-contrast look. It uses a manual-wind movement and places the tourbillon prominently on the dial. The F.A. Jones signature at 3 oclock is one of the watch's defining details, and the black dial adds a restrained counterpoint to the weight and brightness of the platinum case. Produced around 2010, the IW544704 was issued in a limited edition of 50 pieces. The 43.1 mm case has substantial wrist presence, but the dial still keeps the open, balanced layout associated with the Portugieser line. Inside is the hand-wound IWC caliber 98900, visible through the caseback and well matched to the watch's traditional mechanical feel. The design is clean and deliberate. The tourbillon draws the eye, but it does not crowd the dial. In platinum with a black dial, the IW544704 takes the Portugieser in a darker, more dramatic direction without losing its classical restraint. For collectors interested in precious metal complications with a clear point of view, it is a strong example of IWC at its most disciplined.
