Due to its extreme rarity, the watch does not have a standard secondary market bracket, though it commands high-seven-figure prices at auction.

It represents the brand’s first water-resistant chronograph featuring a screw-down case back and round pump pushers, distinguishing it from earlier snap-back models. The 1463J variant is cased in 18k yellow gold and typically houses the manual-wind Caliber 13-130, a movement based on a Valjoux ebauche. Collectors prioritize this reference for its 35mm \"Tasti Tondi\" case design, characterized by sunburst-patterned pusher caps. While total production across all metals is estimated at roughly 750 units, the yellow gold version is the most common. On the secondary market, prices generally range from $150,000 to over $250,000 depending on dial configuration and case condition. Notable examples include those retailed by Tiffany & Co. or Serpico y Laino, which command significant premiums at auction due to their double-signed dials."}, "score": 24, "why_compare": "Same patek philippe collector universe; shared search intent: 18k, chronograph; similar gold case profile.", "listing_stats": {"count": 62, "median": 79500.0, "low": 39500.0, "high": 345000.0, "brands": 1, "merchants": 4}, "top_listing": {"id": "h_7447778787415", "title": "Patek Philippe Patek Philippe Chronograph", "brand": "Patek Philippe", "model": "Patek Philippe Chronograph", "reference": "40930708", "price_usd": 194950.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Chronograph"], "merchant_slug": "analog-shift", "merchant_name": "Analog/Shift", "image_url": "https://cdn.shopify.com/s/files/1/0809/1255/files/AS10810_40930708_PATEKPHILIPPE_COMPLICATIONS_5070P-001-5.jpg?v=1758041287", "detail_url": "https://mostexpensivewatches.net/listing/h_7447778787415", "buy_url": "https://mostexpensivewatches.net/out/h_7447778787415", "available": true}, "auction_comp_count": 1, "review_url": "https://mostexpensivewatches.net/fr/review/patek-philippe-1463j", "alternatives_url": "https://mostexpensivewatches.net/fr/alternatives/patek-philippe-1463j"}, {"reference": {"slug": "patek-philippe-5013r", "brand": "Patek Philippe", "ref": "5013R", "model": "Minute Repeating Perpetual Calendar", "case_material": "18k Pink Gold", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/patek-philippe-5013r", "description": "The Patek Philippe Reference 5013R was produced between 1992 and 2010, representing one of the brand's most complex watches prior to the release of the Sky Moon Tourbillon.

It features the self-winding Caliber R 27 PS QR, which integrates a minute repeater, a perpetual calendar with a retrograde date hand, and a moon phase indicator.

On the secondary market, this reference typically commands prices between $450,000 and $650,000 depending on provenance and condition.
