Collectors prioritize this reference for its 33mm Calatrava-style case featuring square pushers and the Valjoux-based manual-wind caliber 13-130. The 18k yellow gold variant is the most common iteration, yet it remains sought after for its historical role in establishing the brand’s mid-century design language. Dials vary significantly, featuring tachymeter, telemeter, or sector scales, with long-signature \"Patek, Philippe & Co\" markings appearing on earlier examples. On the secondary market, standard 18k yellow gold specimens typically trade in the $40,000 to $80,000 range, though rare dial configurations or exceptional condition can drive prices higher. A notable production variant includes the \"monopusher\" version, which utilizes a single button integrated into the crown to control all chronograph functions, representing a distinct rarity within the reference's thirty-year history."}, "listing_stats": {"count": 1, "median": 35900.0, "low": 35900.0, "high": 35900.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_16184932335961", "title": "Patek Philippe Patek Philippe World Time ref 5130R Guilloché Dial in 18k Rose Gold with Box and Papers", "brand": "Patek Philippe", "model": "Patek Philippe World Time ref 5130R Guilloché Dial in 18k Rose Gold with Box and Papers", "reference": "5130R", "price_usd": 35900.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Rose Gold", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["GMT / Dual Time", "World Time"], "merchant_slug": "bulang-and-sons", "merchant_name": "Bulang & Sons", "image_url": "https://cdn.shopify.com/s/files/1/0961/8613/8969/files/W-3642PatekPhilippeWorldtimeref5130Rwithboxandpapers_274_1x1_244b1467-2899-4b65-a987-9b947955d407.jpg?v=1778666700", "detail_url": "https://mostexpensivewatches.net/listing/h_16184932335961", "buy_url": "https://mostexpensivewatches.net/out/h_16184932335961", "available": true}], "auction_lots": [{"slug": "patek-philippe-130-sector-dial", "brand": "Patek Philippe", "reference": "130", "model": "Sector Dial Chronograph", "case_material": "Stainless Steel", "hammer_usd": 350000, "year_sold": 2016, "venue": "Phillips Geneva", "lot_summary": "A stunning example of the reference 130 featuring a two-tone sector dial.
