Collectors prioritize this reference for its heavy 18k yellow gold construction and the inclusion of the Calibre 352 or 354 \"bumper\" automatic chronometer movements. Key aesthetic features often include \"clous de Paris\" or waffle-textured dials, applied gold arrowhead markers, and substantial faceted lugs. Because these solid gold variants were produced in significantly lower volumes than their steel counterparts, they occupy a specialized niche in vintage Omega collecting. Current secondary market prices typically range from $4,000 to $9,000 depending on the dial condition and case sharpness. A notable production detail is the \"OT\" designation itself, which Omega used in its internal coding to signify a solid 18k gold case, distinguishing it from the gold-capped \"KO\" or \"GX\" variants of the same era."}, "listing_stats": {"count": 322, "median": 4900.0, "low": 3000.0, "high": 39500.0, "brands": 1, "merchants": 6}, "listings": [{"id": "h_7140349018221", "title": "OMEGA 1967 Omega Seamaster 300 (Ref. 165.024) \"W10 British Royal Army\"", "brand": "OMEGA", "model": "1967 Omega Seamaster 300 (Ref. 165.024) \"W10 British Royal Army\"", "reference": "165.024", "price_usd": 39500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "craft-and-tailored", "merchant_name": "Craft + Tailored", "image_url": "https://cdn.shopify.com/s/files/1/1104/9180/files/Img022424_7a254205-f25e-401e-ba8e-2c5cd250222a.jpg?v=1699052877", "detail_url": "https://mostexpensivewatches.net/listing/h_7140349018221", "buy_url": "https://mostexpensivewatches.net/out/h_7140349018221", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7140349018221/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7140349018221/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_7140349018221/via/farfetch"}], "available": true}, {"id": "h_15981138739545", "title": "OMEGA Omega Seamaster 300 British Royal Navy issued ref. 165.024 Mill Spec Circle-T Dial", "brand": "OMEGA", "model": "Omega Seamaster 300 British Royal Navy issued ref. 165.024 Mill Spec Circle-T Dial", "reference": "165.024", "price_usd": 29900.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "bulang-and-sons", "merchant_name": "Bulang & Sons", "image_url": "https://cdn.shopify.com/s/files/1/0961/8613/8969/files/W-3465OmegaSeamaster300Bigtriangleissuedref165024_0008_1x1_354c1946-9784-4235-bec7-23bc1a3c8a97.jpg?v=1790685519", "detail_url": "https://mostexpensivewatches.net/listing/h_15981138739545", "buy_url": "https://mostexpensivewatches.net/out/h_15981138739545", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_15981138739545/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_15981138739545/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_15981138739545/via/farfetch"}], "available": true}, {"id": "h_7278109458566", "title": "OMEGA Stainless steel OMEGA '1st Generation' Seamaster 300 automatic wristwatch with enamel bezel.
