IWC Portofino IW356523
Understated, elegant, and timeless, the IWC Portofino Automatic Ref. IW356523 embodies the quintessence of classic style from the Schaffhausen-based manufacturer. With its sleek design, silver-plated dial with an opaline finish, and ultra-slim profile, this watch impresses with its refined understated style and versatility, whether worn formally or casually.
The perfectly proportioned 40 mm stainless steel case is mounted on a black IWC-signed alligator strap with a pin buckle. The minimalist dial is enhanced with stick indexes, a central seconds hand, and a discreet date window at 3 o'clock, providing clear and elegant reading. The entire piece is protected by a slightly domed sapphire crystal, which has a few superficial micro-scratches, without affecting the readability or the model's charm.
On the movement side, this Portofino is powered by an IWC 35111 automatic caliber, derived from the Sellita SW300, offering 42 hours of power reserve and excellent reliability in a slim and neat format.
Currently available in Geneva, this certified luxury watch is offered in very good overall condition, delivered with its original IWC box and warranty card. It benefits from certified pre-owned status, with full verification of its authenticity and functionality.
The IWC Portofino IW356523 is a pre-owned watch in Geneva perfect for those looking for an elegant, reliable and timeless timepiece, while maintaining excellent value for money in the fine watchmaking segment.
