The IWC Portofino | family history
IWC named its dress watch family after Portofino, the Italian Riviera fishing village that became a postwar symbol of elegant leisure. Launched in 1984, the Portofino positioned IWC in dress-watch territory alongside the Portugieser but with a different character: where the Portugieser derives from a 1939 pocket-watch movement commission and wears as a large-format precision instrument, the Portofino is rounder, softer, and more conventionally elegant. The current generation on in-house movements makes a strong case as the most accessible true IWC manufacture watch available.
IWC’s pared-back round dress family: Roman numerals, slim cases, the brand’s longest-running quiet line. Named for the Ligurian fishing village. The Portofino Chronograph 391xxx generation is the contemporary archetype.
1984–2011 · The original Portofino: ETA-based dress watch
The original Portofino family launched in 1984 as IWC's answer to the market for elegant round dress watches. Early production ran on ETA movements; the design was classical: clean dial, applied indices, leather strap. The Portofino Automatic and Hand-Wound variants established the family template. Through the late 1990s and 2000s, IWC updated the movements but maintained the round case, 39-42mm sizing, and the soft aesthetic that distinguished the Portofino from the more instrument-adjacent Pilot and Portugieser.

2013–present · The Automatic 40: in-house caliber 35111
The current Portofino Automatic 40 (IW358305, 2019–present) runs caliber 35111: an in-house automatic developed specifically for the smaller 40mm case. 42-hour power reserve, date function, display back. The 40mm case is the sweet spot for the Portofino: large enough to wear comfortably on most wrists but small enough to disappear under a shirt cuff. Available in steel with white, blue, or silver dials; the blue dial (IW358305) is the most-collected current reference.
2011–present · The Chronograph: caliber 79350 in a 42mm case
The Portofino Chronograph (IW391022 and current variants) is 42mm with caliber 79350: a column-wheel automatic chronograph with 46-hour reserve. The sub-register layout is cleaner than the Pilot Chronograph's aviation-instrument version: two sub-registers at 3 and 9, tachymetre scale, a date at 6. The Portofino Chrono is the choice for buyers who want a dress chronograph that works in formal contexts where the sport-chronograph aesthetic of the Pilot Chrono would be wrong.
How to read this family
Three honest questions for any Portofino buyer:
- Portofino or Portugieser: what is actually different? The Portugieser is historically a large-format precision watch derived from a pocket-watch commission; the 42mm case, the railway-track minute ring, and the large Arabic numerals read as an instrument. The Portofino is smaller (40mm), rounder, quieter in design, and reads as a classical dress watch. Both carry in-house IWC movements. For buyers who want IWC's movement quality in a watch that works with a suit without the large-case Portugieser scale, the Portofino is the correct choice. For buyers who want the bold large-dial statement, Portugieser.
- Is the in-house caliber 35111 worth the price over ETA-based predecessors? The caliber 35111 is IWC's own, not an ETA base. It is designed specifically for the 40mm Portofino case, so the proportions are correct and the movement design is IWC's intellectual property. For buyers who care about in-house credentials, yes, it is worth the price premium over the older ETA-based Portofinos available cheaply on the secondary market. For buyers who want the dress-watch aesthetic on a reliable automatic and are indifferent to movement provenance, the older ETA-based Portofinos offer honest value.
- Portofino or Calatrava for a dress watch buyer choosing between IWC and Patek? The Calatrava (ref. 6119R) is manual-wind, rose gold, and carries the Patek name and secondhand market at a higher price tier. The Portofino Automatic 40 is steel, automatic, and available at retail without waitlists. Both are round dress watches from credible manufactures; the Portofino is the more accessible and more versatile daily wear. The Calatrava is the aspirational reference that outperforms the Portofino on secondary-market prestige. If you are buying to wear daily and do not want a precious-metal watch, Portofino is the honest answer.

Which ref to buy
The Portofino is IWC's Italian-influenced dress line -- simple dials, elegant proportions, and the cleanest case design in the IWC catalog. The automatic 40mm is the pure dress variant; the Chronograph adds the Pellaton automatic winding mechanism with ceramic pawl wheels. Both use the Caliber 35110 family. The automatic is more versatile; the chronograph is more technically interesting.

IWC Portofino Automatic 40mm -- the definitive IWC dress watch, nothing extraneous.
- The case for it:
- The Portofino Auto 40 has one of the cleanest dial layouts in Swiss watchmaking at this price point. Two-tone sunburst dial, thin case, applied indices. The Cal. 35111 is reliable and the Pellaton automatic winding is practical. For an IWC dress watch without the complications or sport pretense, this is the right choice.
- Consider instead if:
- The Portofino Auto is expensive for what it is mechanically -- the movement is a modified ETA 2892 at the core. Longines Master Collection buys similar dress-watch presence with more movement content for less money.
- 2Open
IWC Portofino Chronograph -- the Pellaton-wound chrono in a dress case, technically more interesting than the automatic.
- The case for it:
- The Pellaton winding system with ceramic pawl wheels is genuinely clever engineering. The chronograph complication is clean on the Portofino dial. For buyers who want a dress chronograph with IWC engineering credibility, this delivers.
- Consider instead if:
- A dress case chronograph is a compromise position -- it lacks the sport utility of the Pilot chronographs and lacks the pure elegance of the simple auto. Buyers who specifically need a formal chrono should look here; buyers who want one watch should choose the automatic.
