IWC Portofino IW391009 42 mm Silver Dial

The 42 mm IW391009 gives the Portofino collection a more substantial wrist presence, with a silver dial set against a stainless-steel Milanaise mesh bracelet. That bracelet changes the watch's attitude: its fluid texture adds a touch of modern polish to the collection's otherwise tailored vocabulary. The date display keeps the dial useful, while the solid caseback and 30-metre water resistance maintain a deliberately urban specification.

Underneath is calibre 75320, an automatic movement based on Sellita SW500 architecture. It contains 240 components and 25 jewels, runs at 4 Hz, and offers 44 hours of power reserve. The movement combines a cam-controlled chronograph with lateral coupling and day-date indication. At 30 mm in diameter, it gives the watch a mechanically substantial foundation suited to its larger case.
