IWC Stainless Steel Portofino Chronograph Ref. IW391016

The IWC Portofino Chronograph Ref. IW391016 presents the collection’s characteristically restrained elegance in a 42mm stainless steel case, paired with an automatic movement for effortless daily wear. Refined yet contemporary, this pre-owned example reflects the Portofino line’s measured approach to design, balancing clean proportions with the added presence of a chronograph. Its black dial is accented by index hour markers and coordinated hands, offering a crisp, legible display against the polished steel architecture. A stainless steel Milanese mesh bracelet enhances the watch’s sophisticated profile, while the deployment clasp provides a secure and streamlined fit. The solid caseback and 30-meter water resistance complete the piece with practical discretion.

The result is a watch that moves seamlessly between classic styling and functional watchmaking, expressing IWC’s enduring aptitude for precision, clarity, and understated luxury.
