About this reference
IW356519 presents the Portofino collection in its cleanest, most restrained form. The 40 mm stainless-steel case is just 9.2 mm thick, giving the white dial and black alligator-leather strap a composed, easy-wearing proportion. A simple date display supplies the useful complication, while the solid caseback and 30-metre water resistance preserve the watch's quietly formal profile.
Its automatic calibre 35111 is built around a 25.6 mm movement with 25 jewels and 163 components. The 4 Hz calibre provides 42 hours of power reserve and displays the date alongside the central hours, minutes and seconds. This IWC Schaffhausen movement uses a Sellita SW300-1 base, giving the compact Portofino a practical mechanical foundation.
