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.

Collectors prioritize this model as a transitional piece featuring the manual-wind Calibre 321 movement and the 39mm straight-lug case design without crown guards. This specific sub-reference is distinguished by its \"Alpha\" hands and the introduction of the \"Dauphine\" style chronograph seconds hand, alongside a \"Base 1000\" or \"Base 500\" tachymeter bezel. Due to its limited production window and historical position as the precursor to the 105.002, market values typically range from $25,000 to over $50,000 depending on the presence of the original \"Dot Over 90\" bezel and dial patination. A notable production detail is that late-series CK2998-62 examples occasionally feature baton hands, marking the aesthetic shift toward the later professional models."}, "score": 18, "why_compare": "Same omega collector universe; shared search intent: omega, stainless; similar steel case profile.", "listing_stats": {"count": 454, "median": 6292.5, "low": 3000.0, "high": 74000.0, "brands": 1, "merchants": 7}, "top_listing": {"id": "h_8029446734146", "title": "OMEGA Speedmaster Moonwatch Omega Co-Axial Master Chronometer Moonphase Chronograph - 44.25 mm Platinum Case - Platinum-Gold Dial - Green Leather Strap - 304.93.44.52.99.003", "brand": "OMEGA", "model": "Speedmaster Moonwatch Omega Co-Axial Master Chronometer Moonphase Chronograph - 44.25 mm Platinum Case - Platinum-Gold Dial - Green Leather Strap - 304.93.44.52.99.003", "reference": "304.93", "price_usd": 54210.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Platinum", "case_size_mm": 25.0, "movement": "Automatic", "complications": ["Chronograph", "Moon Phase"], "merchant_slug": "watch-affinity", "merchant_name": "Watch-Affinity", "image_url": "https://cdn.shopify.com/s/files/1/0683/2449/1586/products/30493445299003.jpg?v=1669756209", "detail_url": "https://mostexpensivewatches.net/listing/h_8029446734146", "buy_url": "https://mostexpensivewatches.net/out/h_8029446734146", "available": true}, "auction_comp_count": 3, "review_url": "https://mostexpensivewatches.net/review/omega-ck2998-62", "alternatives_url": "https://mostexpensivewatches.net/alternatives/omega-ck2998-62"}, {"reference": {"slug": "omega-st376", "brand": "Omega", "ref": "ST376", "model": "Speedmaster", "case_material": "Stainless Steel", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/omega-st376", "description": "The Omega Speedmaster reference ST376.0822 was produced for a brief period starting in 1987, with total production estimated at approximately 1,300 to 2,000 units.

The watch features a 42mm stainless steel case that is thicker than the standard Moonwatch to accommodate the central minute chronograph hand and day-date complications.

It houses the manual-wind Calibre 861 movement. Unlike standard commercial models, these watches were delivered directly to NASA and feature specific military-style engravings on the caseback, including the NASA serial number. Due to its extreme rarity and documented provenance in space exploration, the reference is highly sought after. On the secondary market, authentic examples typically command prices in the mid-to-high five-figure range, though exceptional specimens have exceeded $150,000 at auction.
