IWC Portugieser Chronograph Ceratanium® IW371631 Watch

IWC introduces the Portugieser Chronograph Ceratanium®, a striking new limited edition that reimagines the brand's iconic 1998 chronograph in a bold all-black execution crafted entirely from Ceratanium®, an advanced IWC-developed material that merges the lightness of titanium with the hardness and scratch resistance of ceramic. This dramatic “dark mode” interpretation features a 41 mm Ceratanium® case, crown, and pushers paired with a deep black dial, matching black appliques and hands, and a textured black rubber strap for a seamless, modern aesthetic. Inside, the IWC-manufactured Calibre 69355 delivers precise, robust performance with a column-wheel controlled chronograph and a 46-hour power reserve. Limited to 1,500 pieces, the Portugieser Chronograph Ceratanium® offers collectors a rare fusion of innovative engineering, sleek monochrome design, and the timeless sophistication that defines the Portugieser line.
