Collectors prioritize this reference for its 38mm stainless steel \"waterproof\" case, which features a screw-down caseback and round pushers, a significant size for the era. It is powered by the manual-wind Caliber 33.3, a high-grade movement derived from Lemania that preceded the 321. The \"Multi-scale\" designation refers to the technical dial layout, which typically includes concentric tachymeter, telemeter, and pulsometer scales in contrasting colors. Due to its limited production and historical position as a predecessor to modern professional chronographs, the 2077-4 is rare. On the secondary market, well-preserved examples generally command prices in the $40,000 to $80,000 range, though exceptional specimens with original multi-color snail dials have reached six figures at auction. A notable variant includes the black dial execution, which often realizes a significant premium over silvered versions."}, "listing_stats": {"count": 2, "median": 7675.0, "low": 5450.0, "high": 9900.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_7570130927703", "title": "OMEGA Omega Speedmaster Spacemaster Z-33", "brand": "OMEGA", "model": "Omega Speedmaster Spacemaster Z-33", "reference": "—", "price_usd": 5450.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Chronograph"], "merchant_slug": "analog-shift", "merchant_name": "Analog/Shift", "image_url": "https://cdn.shopify.com/s/files/1/0809/1255/files/AS10756_40960282_OMEGA_SPACEMASTERZ-33_325.92.43.79.01.002-6.jpg?v=1786562727", "detail_url": "https://mostexpensivewatches.net/listing/h_7570130927703", "buy_url": "https://mostexpensivewatches.net/out/h_7570130927703", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7570130927703/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7570130927703/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_7570130927703/via/farfetch"}], "available": true}, {"id": "h_16445538566489", "title": "OMEGA Omega Multiscale Dial Chronograph Cal 28.9", "brand": "OMEGA", "model": "Omega Multiscale Dial Chronograph Cal 28.9", "reference": "W-3799", "price_usd": 9900.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Chronograph"], "merchant_slug": "bulang-and-sons", "merchant_name": "Bulang & Sons", "image_url": "https://cdn.shopify.com/s/files/1/0961/8613/8969/files/W-3799OmegaMultiscaledialchronograph_242_1x1_92eacbe0-f82d-44f1-9243-d01a381f4fa9.jpg?v=1784710208", "detail_url": "https://mostexpensivewatches.net/listing/h_16445538566489", "buy_url": "https://mostexpensivewatches.net/out/h_16445538566489", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_16445538566489/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_16445538566489/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_16445538566489/via/farfetch"}], "available": false}], "auction_lots": [{"slug": "omega-2077-4-2019", "brand": "Omega", "reference": "2077-4", "model": "Chronograph Multi-scale", "case_material": "Stainless Steel", "hammer_usd": 33000, "year_sold": 2019, "venue": "Phillips Geneva", "lot_summary": "An oversized 38mm chronograph from 1945 featuring a complex multi-scale dial with both tachymeter and pulsation scales.", "source_url": "https://www.phillips.com/detail/omega/CH080219/187", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/omega-2077-4-2019"}]}
