IWC Portugieser Automatic Steel — Silver-Plated Dial | Ref. IW500712

The Portugieser Automatic in stainless steel represents something of an ideal entry point into one of IWC's most historically resonant collections. Reference IW500712 presents the full technical specification of the Portugieser — Calibre 52010 with its 168-hour Pellaton-driven power reserve, the railroad-track minute chapter ring, the small seconds at six o'clock — in a case material that prioritises wearability and longevity over precious-metal provenance. The 42.3 mm diameter and 14.2 mm height are unchanged from the gold variants, honouring the Portugieser's pocket-watch dimension rationale.

Calibre 52010 is a movement of genuine distinction. The bidirectional Pellaton ratchet-pawl winding system extracts maximum efficiency from rotor motion, feeding a mainspring capable of sustaining a full week of operation. The power reserve indicator on the silver-plated dial allows the owner to monitor energy status at a glance — a practical consideration for a movement of this reserve capacity. German silver plates and bridges visible through the exhibition caseback are finished to a standard that reflects IWC's Germanic watchmaking tradition, a lineage that traces directly to Florentine Ariosto Jones's founding vision of 1868.

The black alligator leather strap maintains the collection's formal register without the premium associated with the gold references. Water resistance of 3 bar is standard for a dress watch of this orientation. For the collector who values movement quality and historical pedigree above material ostentation, the IW500712 makes a persuasive case: the best of the Portugieser's mechanical substance, presented with understated confidence in Probus Scafusia steel.
