The dial is finished in rare hand-guilloché blue green swirl pattern with Grand Feu enamel and features diamond-set hour markers. Because it is a unique piece, there is no established secondary market price range; however, it sold at auction in May 2024 for 15.7 million CHF. This specific reference is valued for its combination of a high-complication movement with a steel case, a pairing Patek Philippe reserves for unique or extremely limited editions."}, "score": 20, "why_compare": "Same patek philippe collector universe; shared search intent: patek, philippe; similar steel case profile.", "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "top_listing": null, "auction_comp_count": 1, "review_url": "https://mostexpensivewatches.net/de/review/patek-philippe-6301a-001", "alternatives_url": "https://mostexpensivewatches.net/de/alternatives/patek-philippe-6301a-001"}, {"reference": {"slug": "patek-philippe-grandmaster-chime-6300a", "brand": "Patek Philippe", "ref": "6300A-010", "model": "Grandmaster Chime", "case_material": "Stainless Steel", "url": "https://mostexpensivewatches.net/reference/patek-philippe-grandmaster-chime-6300a", "description": "The Patek Philippe Grandmaster Chime reference 6300A-010 was produced as a unique piece specifically for the 2019 Only Watch charity auction. This reference is the only version of the Grandmaster Chime ever manufactured in stainless steel, a metal rarely used by the brand for its high complications. It features the caliber 300 GS AL 36-750 QIS FUS IRM movement, incorporating twenty complications including five acoustic functions: a grande and petite sonnerie, a minute repeater, an alarm with time strike, and a date repeater. The reversible case houses two dials: one in rose gold (salmon) displaying the time and sonnerie details, and another in black ebony for the perpetual calendar. In November 2019, the watch sold at Christie’s Geneva for 31 million Swiss francs, establishing it as the most expensive timepiece ever sold at auction. Because it is a unique piece, it remains in a private collection and does not have a standard secondary market price range."}, "score": 20, "why_compare": "Same patek philippe collector universe; shared search intent: patek, philippe; similar steel case profile.", "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "top_listing": null, "auction_comp_count": 1, "review_url": "https://mostexpensivewatches.net/de/review/patek-philippe-grandmaster-chime-6300a", "alternatives_url": "https://mostexpensivewatches.net/de/alternatives/patek-philippe-grandmaster-chime-6300a"}]}
