Collectors prioritize this reference because it contains a historical Angelus SF240 manual-wind movement, a caliber originally used in vintage Panerai watches from the 1950s. The 47mm stainless steel case features a tobacco brown sandwich dial with a \"8 Giorni Brevettato\" inscription at the 3 o'clock position, referencing the eight-day power reserve. This model is no longer in production and represents a bridge between modern manufacturing and mid-century military components. On the secondary market, the PAM00203 typically commands prices in the $40,000 to $60,000 range, depending on condition and the presence of original documentation. A notable production detail is that the movements were sourced from vintage stock, refurbished, and finished with a circular graining pattern specifically for this release."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "panerai-gpf-2-56-2020", "brand": "Panerai", "reference": "GPF 2/56", "model": "Radiomir 8 Giorni Brevettato 'Egiziano'", "case_material": "Stainless Steel", "hammer_usd": 178000, "year_sold": 2020, "venue": "Phillips Hong Kong", "lot_summary": "A massive 60mm professional diving tool watch developed for the Egyptian Navy, featuring an Angelus 240 8-day movement.", "source_url": "https://www.phillips.com/detail/panerai/HK080220/877", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/panerai-gpf-2-56-2020"}, {"slug": "panerai-gpf-2-56-2015", "brand": "Panerai", "reference": "GPF 2/56", "model": "Radiomir 'Big Egiziano'", "case_material": "Stainless Steel", "hammer_usd": 163333, "year_sold": 2015, "venue": "Christie's Geneva", "lot_summary": "An oversized 60mm diver's watch with an 8-day Angelus movement, originally produced for the Egyptian Navy in the mid-1950s.", "source_url": "https://www.christies.com/en/lot/lot-5945174", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/panerai-gpf-2-56-2015"}]}
