Portugieser Automatic 40

The IW358303 is the 40mm steel Portugieser Automatic, IWC's answer to collectors who wanted the clean, dial-forward design of the Portugieser in a size that actually works on most wrists. It runs the Pellaton-wound caliber 82200, an IWC-developed movement with 60 hours of reserve and a reputation for efficient, reliable winding. For buyers who found the traditional 42mm Portugieser too large for daily wear, this reference is the practical entry into the line.

What it is

IWC introduced the 40mm Portugieser Automatic in 2020, positioning it as a more accessible alternative to the long-running 42mm references. The reference 7300 family at 42mm had defined the modern Portugieser for years; the 40mm IW358303 brought the same minimalist dial language and cathedral hands to a case that competes more directly with Rolex Datejust and Grand Seiko sizing conventions. The caliber 82200 uses IWC's Pellaton winding mechanism, a pawl-wheel system that winds in both directions with notably low slippage.

No significant dial or case variants have shipped on this reference since introduction; the main choice is between the silver and blue dial options available at retail.

Buying notes

Inspect the crown closely. The Portugieser's slim, screw-down crown is a wear point and replacements are not cheap. Ask for service records and confirm the movement was last pressure-tested within the past three to four years.

Dial condition matters disproportionately on this watch because the minimalist layout means any fading, printing wear at the "IWC SCHAFFHAUSEN" text, or lume degradation on the cathedral hands is immediately visible. The leather strap from IWC wears quickly in humid climates; budget for a quality aftermarket replacement or a steel bracelet if you plan daily wear. Confirm the reference number rather than going by seller description, as the 42mm IW500710 family trades at a different price and some listings conflate them.

Market read

New retail lands around $5,500 to $6,000 USD depending on configuration, and the secondary market has settled slightly below retail for lightly worn examples, typically $4,200 to $5,000 for clean specimens with box and papers. The 40mm reference does not command the same collector premium as vintage Portugiesers or the large complications, so buyers benefit from a buyer's market. Blue dial examples carry a modest premium of $200 to $400 over silver dial on the secondary market.

Waiting lists at authorized dealers are essentially gone post-2023, which keeps grey market pricing honest.

Service expectations

The caliber 82200 carries an IWC-recommended service interval of around eight to ten years under normal wear. Expect full service at an IWC service center to run $600 to $900 USD; independent watchmakers familiar with IWC movements can do it for $400 to $600 with access to correct parts. The Pellaton winding system is not difficult to service but requires proper tooling, so vet any independent before handing over the watch.
