Key Features

• The Sovereign Peak of Schaffhausen Executive Minimalism: Introduced in the golden late-century era of the International Watch Co., the IWC Portofino Automatic reference 3513 represents the quintessential expression of pure Swiss dress watch restraint. Named after the picturesque Italian coastal village, this iconic reference was conceived to channel timeless mid-century pocket watch aesthetics into a refined, modern automatic wrist instrument engineered for understated luxury.
• The Proven 21-Jewel Caliber 37521 Automatic Heart: Powering this classic timepiece is the highly regarded 21-jewel Caliber 37521 (or Caliber 37524, built on the ultra-reliable ETA 2892-A2 base), finely hand-finished and elevated in-house by IWC Schaffhausen to chronometer-grade tolerances. Operating at a high frequency of 28,800 vibrations per hour (4 Hz), the ultra-slim caliber incorporates a 21-jewel specification, bidirectional automatic rotor winding, hacking seconds, rapid quick-set date correction, and approximately 42 hours of power reserve.
• Architectural ""3513"" Stepped Round Case Profile: Crafted in solid stainless steel (or 18k yellow gold), the reference 3513 features an iconic 34mm circular case defined by its stepped, rounded bezel and short, elegant straight-drop lugs reminiscent of classic wire-lug pocket watch conversions. Engineered with an ultra-thin profile under 9mm in height, the case sits flush against the wrist, sliding effortlessly beneath a tailored shirt cuff.
• Masterful Pure-Time Dial Harmony and Roman Typography: The dial of the 3513 is universally celebrated for its harmonious, uncluttered layout, featuring a clean lacquer white or enamel-effect dial bordered by a discrete outer minute track. It is accented by hand-applied, polished baton indices with Roman numerals at 12 and 6, slender polished feuille (leaf) hands, a cleanly framed date aperture at 3 o'clock, and the traditional cursive ""International Watch Co. Schaffhausen"" script.
• An Investment-Grade Classic of Modern Neo-Vintage Swiss Horology: Serving as the cornerstone design that cemented the Portofino collection within IWC's core portfolio, the reference 3513 stands as a universally admired, highly collectible dress watch. Embodying the pristine balance of Swiss mechanical reliability, slender case ergonomics, and pure executive styling, it remains an enduring heirloom of Schaffhausen watchmaking heritage.
