Portugieser Chronograph Ceratanium

A creative reimagining of a timeless classic, the Portugieser Chronograph Ceratanium marks the first appearance of this distinctively dark material in the Portugieser collection. The all-black, monolithic 41mm case, crown, and pushers are made entirely from Ceratanium - an IWC-developed material combining titanium's lightness with ceramic-like hardness and a dark metallic finish that needs no additional coating. The design is enhanced with a black dial, black appliques, black hands, and a black textured rubber strap with a square pattern, secured by a Ceratanium buckle. Features include small hacking seconds and a chronograph function (minutes and seconds), viewed through convex sapphire glass with antireflective coating on both sides; the case back is fitted with synthetic sapphire crystal. Case height is 13mm, strap width 20mm, buckle width 18mm, water resistance 3 bar. Powering the watch is IWC's automatic Caliber 69355 (205 components, 27 jewels) at 28,800 vph (4 Hz) with a 46-hour power reserve. Limited to 1,500 pieces.
