The Portofino Automatic 40mm is IWC's cleanest dress watch at the most accessible entry point in the lineup. Its slim case, restrained dial, and small seconds at 9 make it a legitimate alternative to Longines or Frederique Constant at a fraction of the Portugieser's price. Collectors who want IWC provenance on the wrist without the bulk of a pilot watch or the expense of the Portugieser start here.
IWC has offered Portofino dress automatics since the 1980s, but the current 40mm generation with the IW356504 reference settled into its mature form around 2019. The caliber 35111 is a modified Sellita SW300-1, which traces its own lineage to the ETA 2892. IWC rates it at 42 hours of power reserve with a frequency of 28,800 vph.
Dial variants across the line include silver, blue, and black, with the silver sunburst being the most requested. No significant references have been discontinued in this generation, though earlier Portofino rounds in 37mm and 39mm represent an older design language that some collectors prefer for its thinner bezel.
The Sellita SW300-1 base is not a secret, and some buyers feel the retail price is hard to justify for what is, mechanically, a mid-tier Swiss lever movement. Inspect the dial carefully: the Portofino's sunburst finish shows fingerprints and fine scratches from careless handling, and a marred dial is the most common discount reason on the grey market. Check the case for polishing.
The lugs on the 40mm are narrow enough that an overzealous polish rounds them quickly and flattens the brushed flanks. Bracelet wear is not an issue since the IW356504 ships on a leather strap, but examine the lug holes for wear if a prior owner used an aftermarket metal bracelet adapter.
