IWC Portugieser Chronograph Steel — Green Dial Black Alligator Strap | Ref. IW371615

Colour has become one of the most powerful differentiating tools in contemporary watch design, and IWC's decision to render the Portugieser Chronograph dial in a rich, saturated green speaks directly to a market that demands personality without sacrificing the collection's essential classical character. The 41.0 mm stainless steel case at 13.1 mm thickness maintains the slender, elegant profile that has made the Portugieser Chronograph a perennial reference point for the genre, and the see-through sapphire caseback continues to provide the movement exhibition that enthusiasts expect at this tier.

Calibre 69355, the in-house column-wheel automatic chronograph movement, delivers approximately 46 hours of power reserve alongside the full complement of chronograph indications. The column wheel mechanism ensures a consistent, satisfying action at the pushers — a tactile quality that distinguishes genuine horological care from merely functional engineering. Small seconds at nine o'clock and the 30-minute counter at three maintain the symmetrical register layout that has defined Portugieser chronograph aesthetics across generations.

The green dial's depth and saturation create a vivid contrast against the polished steel case and the warm tones of the black alligator leather strap — a combination that positions this reference as the bolder, more contemporary expression of the Portugieser Chronograph lineage without abandoning its architectural roots. The premium of 830 USD over the silver-dialled bracelet variant reflects the additional desirability that a striking dial colour commands in the current market. For the collector seeking a Portugieser Chronograph that carries visual conviction without veering into the territory of complications, Ref. IW371615 is the answer. Water resistance to 3 bar.
