Omega Chronograph Multi-scale

About this reference

The Omega reference 2077-4 is a vintage chronograph produced during the early to mid-1940s. 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.
