It features a 40mm case and integrated bracelet crafted from 18k white gold, housing the ultra-thin self-winding caliber 240 Q. This movement allows the case to maintain a profile of 8.42mm, making it the thinnest perpetual calendar in the brand's catalog. The dial is finished in blue sunburst with horizontal embossing and features three sub-dials indicating the day, date, month, leap year, 24-hour cycle, and moon phases. On the secondary market, this reference typically commands prices in the mid-to-high six-figure range, often fluctuating between $210,000 and $260,000 depending on condition and provenance. A notable production detail is the inclusion of the fold-over clasp with four independent catches for improved security compared to earlier Nautilus iterations."}, "listing_stats": {"count": 1, "median": 265000.0, "low": 265000.0, "high": 265000.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_6861942915281", "title": "Patek Philippe Patek Philippe Nautilus 5740/1G-001", "brand": "Patek Philippe", "model": "Patek Philippe Nautilus 5740/1G-001", "reference": "5740/1G-001", "price_usd": 265000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k White Gold", "case_size_mm": 40.5, "movement": "Automatic", "complications": [], "merchant_slug": "material-good", "merchant_name": "Material Good", "image_url": "https://cdn.shopify.com/s/files/1/0561/5190/0369/files/Patek_Philippe_Nautilus_5740_1G-001.jpg?v=1777673815", "detail_url": "https://mostexpensivewatches.net/listing/h_6861942915281", "buy_url": "https://mostexpensivewatches.net/out/h_6861942915281", "available": true}], "auction_lots": []}
