About This Watch
The IWC Portugieser Tourbillon Hand-Wound IW546301 showcases IWC's mastery of Tourbillon watchmaking. Housing the IWC 54900 with a 43mm 18K Rose Gold case, this timepiece delivers both performance and presence on the wrist. The tourbillon complication represents one of horology's greatest technical achievements, rotating the escapement to counteract gravity's effects on timekeeping. Water resistant to 30 meters and priced at $85,000 MSRP, it represents compelling value in its segment. IWC Schaffhausen combines precise Swiss engineering with distinctive design, creating timepieces that are equally at home in a cockpit or a boardroom.
