Schaffhausen, February 26th, 2026: IWC Schaffhausen unveils the Portugieser Chronograph Ceratanium®. Entering dark mode, the iconic chronograph is presented in an all-black version crafted in Ceratanium®, an IWC-developed material that combines lightness and hardness with a distinctive dark finish. Alongside the Ceratanium® case, crown, and pushers, the watch features a black dial with black appliques and hands, and a rubber strap in the same shade. The Portugieser Chronograph Ceratanium® is presented in a limited edition of 1,500 pieces.
Since its introduction in 1998, the Portugieser Chronograph has brought a touch of sporty elegance to IWC Schaffhausen’s Portugieser collection. With its two vertically arranged subdials and an inner flange with a quarter-second scale, the chronograph has established itself as one of the Swiss luxury watchmaker’s most recognizable and popular watch designs. IWC now presents a creative reimagining of this timeless classic: the first all-black version crafted from Ceratanium®.
With its clean, pure and timelessly relevant aesthetic, the Portugieser Chronograph has captivated me from the beginning. I am excited to combine this unique design with Ceratanium®, one of our most significant material innovations. The all-black execution is different from anything we have ever done before. It emphasizes the chronograph’s mere shape, ensuring that nothing distracts the eye from its distinctive silhouette.
Limited to 1,500 pieces, the Portugieser Chronograph Ceratanium® (Ref. IW371631) features a 41-millimetre case, crown and pushers crafted from Ceratanium®. Developed by IWC, this advanced material combines the lightness and robustness of titanium with a hardness and scratch-resistance similar to that of ceramic. Another characteristic of Ceratanium®, which is based on a special titanium alloy and fired at high temperatures in a kiln, is its distinctive, dark and metallic finish. The all-black design of the chronograph is further enhanced with a black dial, black appliques and black hands. The applied Arabic numerals, indices and quarter-second scale are discreet elevations against the background of the black dial. A black rubber strap with a square pattern complements the monolithic look of this watch.
ROBUST AND RELIABLE CHRONOGRAPH MOVEMENT
The Portugieser Chronograph Ceratanium® is powered by the IWC-manufactured 69355 calibre, a mechanical chronograph movement engineered with a focus on robustness, reliability and longevity. The column-wheel control mechanism for the chronograph function provides clearly defined phases in the switching sequence and offers distinct tactile feedback when the buttons are pressed. The movement features an automatic doublepawl winding system, which reliably builds up a power reserve of 46 hours in the mainspring.
The Portugieser line traces its origins to IWC's 1939 pocket watch-inspired wristwatches, originally developed for Portuguese merchants seeking precision timekeeping. This collection has remained central to IWC's identity for over eight decades, evolving from simple time-only pieces to sophisticated chronographs while maintaining the characteristic clean dial architecture and oversized Arabic numerals that defined the original concept.
The introduction of Ceratanium represents a significant materials innovation for IWC, combining titanium's lightweight properties with ceramic's scratch resistance and distinctive matte finish. The case construction utilizes IWC's proprietary alloy that can be machined like titanium but achieves ceramic's hardness through specialized treatment. The chronograph function is driven by IWC's caliber 69355, a robust movement that provides reliable timing capabilities while maintaining the collection's signature legible dial layout with contrasting subdials.
This Ceratanium variant positions itself at the premium end of the Portugieser chronograph range, appealing to collectors seeking both technical innovation and understated luxury. The all-black aesthetic and advanced materials make it particularly relevant for contemporary tastes while honoring the collection's historical DNA. Limited availability and IWC's strategic focus on materials development suggest strong collectible potential, particularly among enthusiasts who value horological innovation over traditional precious metal construction.
That you will be able to buy this watch 50% cheaper in a year or two. That’s the IWC conundrum
Surely IWC can do better. Maybe not 20bar with pump pushers like Sinn but at least 10bar would be nice. Makes the whole tech mumbo-jumbo a bit comical.
and I could start considering it
