IWC Portugieser Automatic 40 Steel — Silver-Plated Dial on Bracelet | Ref. IW358312

Reference IW358312 presents the Portugieser Automatic 40 in its most urbane configuration: a 40.4 mm stainless steel case paired with an integrated steel bracelet rather than the leather strap typically associated with this collection's classical heritage. The choice transforms the character of what is ostensibly a shared platform with its strap-wearing sibling — where the alligator variant reads as a dress watch of traditional inclination, the bracelet reference asserts a more contemporary, multipurpose personality suited to the professional who transitions directly from desk to dinner without a change of wrist. The case remains a precise 12.3 mm in depth, maintaining the discretion that distinguishes the Portugieser from brasher sport offerings.

Calibre 82200 drives the display with the same 60-hour power reserve that distinguishes this generation of Portugieser movements — a significant advance over the ébauches that earlier occupied these cases and a figure that provides meaningful multi-day autonomy. The silver-plated dial adheres to the established grammar: Breguet-style Roman numerals, a precisely scaled railway-track minute ring, and small seconds at nine o'clock, arranged with the compositional discipline that has defined the Portugieser since the original oversized navigational instruments of the 1930s. A see-through caseback reveals the movement and its decorated bridges.

The convex sapphire crystal with double-sided anti-reflective coating ensures excellent dial legibility regardless of ambient conditions, while water resistance to 3 bar represents the standard for this dress-adjacent category. At $6,970, the bracelet configuration carries a modest premium over the strap version — a transparent pricing logic given the material and manufacturing investment of the steel bracelet — and offers the collector a single versatile reference where previously two watches might have been considered necessary.
