IWC SCHAFFHAUSEN Presents The Portugieser Chronograph

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®.

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.
