About this watch
The IWC Portugieser Regulateur IW5444-01 is a masterpiece of luxury watchmaking. Founded in 1868, IWC has been a pioneer in precision timepieces, and the Portugieser family, introduced in the 1930s, is renowned for its nautical heritage and elegant aesthetics. This unique model showcases a regulator-type display that sets it apart from traditional designs. The round stainless steel case has a polished finish that gleams under any light, with a diameter of 43.10 mm and a height of 11.80 mm. The silver dial is a canvas for Arabic numeral indexes, while the hands, crafted in the elegant feuille style, provide a classic touch. The watch's comfort is key, designed to sit snugly on the wrist with an ergonomic design and lug width of 22.00 mm. With a water resistance rating of 30 meters, it can withstand splashes and brief immersion. The IWC Portugieser Regulateur IW5444-01 is powered by the IWC Caliber 98245, a handwound movement that brings precision and reliability to the table. This watch is not just a timepiece; it's a statement piece of art that encapsulates the essence of IWC's dedication to quality and innovation.
