Collectors prioritize this reference for its caliber 353 or 355 bumper automatic movement and the distinct six o'clock position of the date window. The 18k pink gold execution is significantly rarer than the steel or gold-capped versions, often featuring heavy \"beefy\" lugs and a screw-down case back. On the secondary market, 18k pink gold examples typically range from $4,000 to $8,500 depending on the presence of original \"waffle\" or \"honeycomb\" dials and sharp case geometry. A notable production detail is the \"Calendar\" text placement, which is often found curved along the bottom of the dial. High-condition specimens with original pink gold crowns and markers have reached the upper end of this bracket at specialized auctions."}, "listing_stats": {"count": 8, "median": 5710.0, "low": 3350.0, "high": 31415.0, "brands": 1, "merchants": 4}, "listings": [{"id": "h_8029406691650", "title": "OMEGA Seamaster Aqua Terra Co-Axial Annual Calendar Watch - 38.5 mm Red Gold Case - Teak-Sun Brushed Grey Dial - 231.50.39.22.06.001", "brand": "OMEGA", "model": "Seamaster Aqua Terra Co-Axial Annual Calendar Watch - 38.5 mm Red Gold Case - Teak-Sun Brushed Grey Dial - 231.50.39.22.06.001", "reference": "231.50", "price_usd": 31415.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 38.5, "movement": "Automatic", "complications": ["Annual Calendar", "Chronograph"], "merchant_slug": "watch-affinity", "merchant_name": "Watch-Affinity", "image_url": "https://cdn.shopify.com/s/files/1/0683/2449/1586/products/23150392206001.jpg?v=1669755816", "detail_url": "https://mostexpensivewatches.net/listing/h_8029406691650", "buy_url": "https://mostexpensivewatches.net/out/h_8029406691650", "available": true}, {"id": "h_8029406560578", "title": "OMEGA Seamaster Aqua Terra Co-Axial Annual Calendar Watch - 38.5 mm Red Gold Case - Teak-Silver Dial - 231.50.39.22.02.001", "brand": "OMEGA", "model": "Seamaster Aqua Terra Co-Axial Annual Calendar Watch - 38.5 mm Red Gold Case - Teak-Silver Dial - 231.50.39.22.02.001", "reference": "231.50", "price_usd": 31415.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 38.5, "movement": "Automatic", "complications": ["Annual Calendar", "Chronograph"], "merchant_slug": "watch-affinity", "merchant_name": "Watch-Affinity", "image_url": "https://cdn.shopify.com/s/files/1/0683/2449/1586/products/23150392202001.jpg?v=1669755814", "detail_url": "https://mostexpensivewatches.net/listing/h_8029406560578", "buy_url": "https://mostexpensivewatches.net/out/h_8029406560578", "available": true}, {"id": "h_8029406888258", "title": "OMEGA Seamaster Aqua Terra Co-Axial Annual Calendar Watch - 43 mm Steel Case - Teak-Silver Dial - 231.10.43.22.02.003", "brand": "OMEGA", "model": "Seamaster Aqua Terra Co-Axial Annual Calendar Watch - 43 mm Steel Case - Teak-Silver Dial - 231.10.43.22.02.003", "reference": "231.10", "price_usd": 7570.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Rose Gold", "case_size_mm": 43.0, "movement": "Automatic", "complications": ["Annual Calendar", "Chronograph"], "merchant_slug": "watch-affinity", "merchant_name": "Watch-Affinity", "image_url": "https://cdn.shopify.com/s/files/1/0683/2449/1586/products/23110432202003.jpg?v=1669755818", "detail_url": "https://mostexpensivewatches.net/listing/h_8029406888258", "buy_url": "https://mostexpensivewatches.net/out/h_8029406888258", "available": true}, {"id": "h_14884332437887", "title": "OMEGA Stainless steel OMEGA Seamaster CALENDAR automatic wristwatch.
