Collectors value this reference as the foundational model of the Portuguese line, characterized by its oversized 41.5mm three-part stainless steel case and the use of the Calibre 74 or Calibre 98 pocket watch movements. The dial typically features a railway-track minute circle and a large sub-seconds dial at six o'clock. Due to its extreme rarity and historical significance as a tool watch commissioned by Portuguese merchants, the Reference 325 occupies the high-five to low-six-figure price bracket on the secondary market. A notable production variant includes the \"Moderne\" dials from the 1940s featuring embossed Arabic numerals. In 2015, a well-preserved steel example achieved a sale price of approximately 80,000 CHF at auction, reflecting its status among vintage collectors."}, "listing_stats": {"count": 34, "median":
