Collectors prioritize this reference as the first civilian chronograph released by Panerai, based on a 1943 prototype. The watch features a 42mm brushed stainless steel case with a fixed tachymeter bezel and a modular ETA 2801-2 movement with a Dubois-Dépraz 3127 chronograph caliber. The dial is navy blue with two sub-dials and tritium-based luminous markers. Production was limited, with approximately 492 units completed out of an initial intended run of 1,000. On the secondary market, these timepieces typically trade between $15,000 and $25,000 depending on the presence of the original mahogany box and paperwork. A notable variant is the \"Slytech\" edition, reference 5218-302/304, which was customized for actor Sylvester Stallone and features distinct dial branding and a higher market premium."}, "listing_stats": {"count": 2, "median": 4575.0, "low": 3550.0, "high": 5600.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_6960396828747", "title": "Panerai Panerai Mare Nostrum Limited Edition PAM 716", "brand": "Panerai", "model": "Panerai Mare Nostrum Limited Edition PAM 716", "reference": "716", "price_usd": 5600.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/files/Panerai-Mare-Nostrum-PAM-716-10-10-PAM-85GBQK-d10511d9557b.jpg?v=1724090050", "detail_url": "https://mostexpensivewatches.net/listing/h_6960396828747", "buy_url": "https://mostexpensivewatches.net/out/h_6960396828747", "available": false}, {"id": "h_6857063268427", "title": "Panerai Panerai Radiomir Black Seal PAM 183", "brand": "Panerai", "model": "Panerai Radiomir Black Seal PAM 183", "reference": "183", "price_usd": 3550.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/products/Panerai-Radiomir-Black-Seal-PAM-183-10-10-PAM-7SCP03-a1fbf103ca96.jpg?v=1695931666", "detail_url": "https://mostexpensivewatches.net/listing/h_6857063268427", "buy_url": "https://mostexpensivewatches.net/out/h_6857063268427", "available": false}], "auction_lots": [{"slug": "panerai-5218-301-a-2008", "brand": "Panerai", "reference": "5218-301/A", "model": "Mare Nostrum", "case_material": "Stainless Steel", "hammer_usd": 21000, "year_sold": 2008, "venue": "Bonhams Hong Kong", "lot_summary": "A rare 'Pre-Vendome' era chronograph, one of the first models released to the public in 1993.", "source_url": "https://www.bonhams.com/auctions/16908/lot/844/", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/panerai-5218-301-a-2008"}]}
