Details & Specifications
Description
The IWC Portofino Automatic ref. 3513 is the quintessential expression of what IWC does best in the dress watch category — a timepiece of pure, uncompromising elegance that relies entirely on proportion, finishing quality, and the authority of the IWC name to make its case, with no complications, no colour, and no ornamentation to distract from the purity of the design. Introduced as part of the Portofino collection — IWC's leisurely, Mediterranean-inspired dress line conceived in the 1980s — the ref. 3513 presents in a stainless steel case of exemplary finish: polished sides, brushed tops, and a smooth domed bezel that frames the white silver-toned dial with quiet confidence.
The dial is an exercise in restraint: applied baton hour indices in polished steel, a fine outer minute track, and the full "IWC International Watch Co. Schaffhausen" three-line script signature in elegant black text — with "Automatic" printed at 6 o'clock and a clean date aperture at 3 o'clock, the only complication present. Polished lance-shaped hands complete a dial layout of genuinely timeless character. The movement within — IWC's Calibre 37526, a well-regarded automatic with Pellaton winding — delivers reliable, precise timekeeping within an elegantly thin case profile that disappears under a shirt cuff with effortless grace.
At approximately 37mm, the case wears with the slim, dressy proportion that defined the finest Swiss watchmaking of the 1990s and remains entirely at home in formal and smart-casual contexts today. Paired with a dark brown crocodile leather strap, this is a supremely wearable, understated piece of Swiss horology from one of the craft's most respected addresses.
