This stainless steel model is valued by collectors for its caliber 50010 movement, which features the Pellaton winding system and a seven-day power reserve displayed at the 3 o’clock position. The 42.3mm case houses a silver-plated dial with applied rose gold Arabic numerals and leaf-shaped hands, a configuration that established the modern aesthetic for the Portugieser line. Unlike its successor, the 5007, the 5001-01 utilizes a slower 2.5Hz beat rate and a single-barrel architecture. On the secondary market, this reference typically trades between $6,500 and $8,500 depending on condition and the presence of original documentation. Early production units are noted for having a \"fish\" crown, which was later replaced by the Probus Scafusia logo, a detail often tracked by brand enthusiasts."}, "listing_stats": {"count": 1, "median": 5400.0, "low": 5400.0, "high": 5400.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_7980367642733", "title": "IWC 2010s IWC Portugieser 7-Day (Ref.
