Collectors prioritize this reference for its 38mm case diameter and the caliber 929/3 movement, which features a power reserve indicator, date sub-dial, and a second time zone linked to a rotating city disc. This model was the first to undergo the brand’s 1,000 Hours Control testing protocol, a standard now applied across their collections. The dial is characterized by its asymmetrical layout and a dedicated aperture at six o'clock for city selection. On the secondary market, stainless steel examples typically trade between $6,000 and $9,000 depending on condition and the inclusion of original documentation. A notable production variant includes the limited edition \"25th Anniversary\" model, though the standard silver dial remains the most common configuration for this reference."}, "listing_stats": {"count": 1, "median": 12500.0, "low": 12500.0, "high": 12500.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_8080503734498", "title": "Jaeger-LeCoultre Jaeger-LeCoultre Master Control | REF. 142.2.92 | 38mm | 18k Rose Gold", "brand": "Jaeger-LeCoultre", "model": "Jaeger-LeCoultre Master Control | REF. 142.2.92 | 38mm | 18k Rose Gold", "reference": "142.2", "price_usd": 12500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Rose Gold", "case_size_mm": 38.0, "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/JLCGMT1.jpg?v=1682354829", "detail_url": "https://mostexpensivewatches.net/listing/h_8080503734498", "buy_url": "https://mostexpensivewatches.net/out/h_8080503734498", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_8080503734498/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_8080503734498/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_8080503734498/via/farfetch"}], "available": false}], "auction_lots": [{"slug": "jaeger-lecoultre-142-8-92-s-2024", "brand": "Jaeger-LeCoultre", "reference": "142.8.92.S", "model": "Master Control Geographic", "case_material": "Stainless Steel", "hammer_usd": 8459, "year_sold": 2024, "venue": "Bonhams London", "lot_summary": "A stainless steel automatic world time wristwatch with date, day/night, and power reserve indication.", "source_url": "https://www.bonhams.com/auctions/29154/lot/112/", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/jaeger-lecoultre-142-8-92-s-2024"}]}
