Due to its larger proportions and technical movement, it is a primary target for vintage Longines enthusiasts. On the secondary market, prices generally range from $12,000 to $25,000 depending on condition and dial configuration.

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."}, "score": 13, "why_compare": "Shared search intent: chronograph, stainless; similar steel case profile.", "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "top_listing": null, "auction_comp_count": 1, "review_url": "https://mostexpensivewatches.net/ar/review/omega-2077-4", "alternatives_url": "https://mostexpensivewatches.net/ar/alternatives/omega-2077-4"}]}
