The Portugieser IW5242-04 (aka: 5242-04, IW524204), seen from the bench
The IW5242-04 Portugieser is a 43 mm platinum 950 watch with a slate dial, featuring the IWC 95290 caliber—a rare minute repeater complication that produces distinct tones for hours, quarters, and minutes. The 18 mm lug width is determined by the case construction and geometry. This model represents the evolution of IWC's historic 1939 Portugieser design for the Portuguese merchant marine.
