Collectors target this reference for its tonneau-shaped stainless steel case, which follows the golden ratio proportions established by Michel Parmigiani. It features the in-house Calibre PF331, an automatic movement with a 55-hour power reserve and twin barrels. The dial typically displays a guilloché pattern with a date aperture at 6 o'clock and delta-shaped hands. This model represents the brand’s foundational design language and is noted for its ergonomic teardrop lugs. On the secondary market, the PF000331 generally trades between $4,500 and $7,500 depending on the presence of the original steel bracelet or leather strap. A notable production detail is the movement's high-level finishing, including Côtes de Genève and perlage, which was uncommon for steel sports-luxury watches in its original price bracket."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "parmigiani-fleurier-pf000331-2024", "brand": "Parmigiani Fleurier", "reference": "PF000331", "model": "Kalpa Grande", "case_material": "Stainless Steel", "hammer_usd": 5022, "year_sold": 2024, "venue": "Phillips Geneva", "lot_summary": "An elegant tonneau-shaped wristwatch powered by the caliber PF 331, the brand's first self-winding mechanical movement.", "source_url": "https://www.phillips.com/detail/parmigiani-fleurier/CH080124/34", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/parmigiani-fleurier-pf000331-2024"}]}
