Unworn IWC Portofino Chronograph 39, Stainless Steel, 39mm, Ref# IW391503, box and papers

Introducing the IWC Portofino Chronograph 39 Ref# IW391503 marks a subtle yet significant milestone for the collection, debuting its first-ever bracelet. Traditionally known for refined minimalism and timeless elegance, the Portofino now gains a dash of casual versatility, bridging dressy sophistication with sporty ease. Its 39mm mirror-polished stainless steel case—compact by IWC standards—offers an upgraded water resistance of 50 metres while retaining the clean, silver-plated dial that defines the line. The layout remains balanced and elegant: slim applied indices with discreet Roman numerals, feuille hands, and recessed sub-dials at 12 and 6 o’clock for the 30-minute chronograph totalizer and small seconds. There’s no date to interrupt the symmetry, and legibility is prioritized despite the absence of lume. The Jubilee-style bracelet, with its alternating polished and brushed finishes, adds a new dimension—making the watch equally at home under a tailored cuff or at a relaxed weekend gathering. Quick-release pins and a butterfly clasp enhance comfort and versatility. Inside beats the IWC-manufactured calibre 69355, a column-wheel chronograph movement offering crisp start/stop action and 46 hours of power reserve, visible through the sapphire case back. Topped with a convex, double AR-coated sapphire crystal, this Portofino blends elegance, practicality, and a touch of modern sportiness in a way that feels both fresh and familiar.
