It is one of only two vintage Rolex references to feature a triple calendar with a moonphase complication, alongside the Oyster-cased 6062. Unlike the 6062, the 8171 features a non-waterproof snap-on case back. The watch utilizes the self-winding Calibre 10.5''' movement. Collectors prioritize the stainless steel variant due to its rarity compared to yellow gold models and the tendency for the snap-back cases to suffer from over-polishing or moisture ingress. Original dials often feature leaf-shaped hands and blue date scales. On the secondary market, steel examples typically command prices in the mid-to-high six-figure range. A notable auction result occurred in 2016 when a highly preserved steel 8171 with a \"line\" dial sold for approximately 1.02 million CHF, illustrating the premium placed on unpolished case condition."}, "listing_stats": {"count": 1, "median": 10750.0, "low": 10750.0, "high": 10750.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_7989020852450", "title": "Rolex Rolex GMT-Master II | REF. 116710LN | Stainless Steel", "brand": "Rolex", "model": "Rolex GMT-Master II | REF. 116710LN | Stainless Steel", "reference": "—", "price_usd": 10750.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["GMT / Dual Time"], "merchant_slug": "watch-collectors-uk", "merchant_name": "Watch Collectors UK", "image_url": "https://cdn.shopify.com/s/files/1/0628/2218/7234/products/Rolex_GMT_Steel_01.jpg?v=1672830072", "detail_url": "https://mostexpensivewatches.net/listing/h_7989020852450", "buy_url": "https://mostexpensivewatches.net/out/h_7989020852450", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7989020852450/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7989020852450/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_7989020852450/via/farfetch"}], "available": false}], "auction_lots": [{"slug": "rolex-8171-2013", "brand": "Rolex", "reference": "8171", "model": "Triple Calendar \"Padellone\"", "case_material": "Stainless Steel", "hammer_usd": 1145000, "year_sold": 2013, "venue": "Christie's New York", "lot_summary": "A rare stainless steel example of the 'Padellone' featuring diamond-set hour markers and a triple calendar moonphase complication.", "source_url": "https://www.christies.com/lot/lot-5755184", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/rolex-8171-2013"}, {"slug": "rolex-8171-2016", "brand": "Rolex", "reference": "8171", "model": "Triple Calendar Moonphase \"Padellone\"", "case_material": "Stainless Steel", "hammer_usd": 1020000, "year_sold": 2016, "venue": "Phillips Hong Kong", "lot_summary": "A pristine stainless steel example of the 'Padellone', setting a record for the most expensive Rolex sold at auction in Asia at the time.", "source_url": "https://www.phillips.com/detail/rolex/HK080216/38", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/rolex-8171-2016"}]}
