An early 1940s Omega chronograph featuring the renowned Cal. 33.3 CHRO, housed in a stainless steel 38mm waterproof case, with a rare black multi-scale dial.
Among scarce waterproof chronographs, this piece is particularly unusual, featuring an early screw-back waterproof case with an engraved caseback and large pushers. It is powered by the oversized Cal. 33.3 CHRO chronograph movement, measuring over 33mm in diameter.
The dial is a complex gilt-produced multi-scale configuration, incorporating a tachymeter (gold), telemeter (pink), snail tachymeter (pink), and a pulsometer (green) set within a white enamel ring.
Compared to contemporaries from brands such as Patek Philippe, Rolex, Longines, Universal Genève, and Movado, this watch stands out for its vividly colored multi-scale dial and large 38mm screw-back waterproof case—showcasing the exceptional design and quality unique to Omega during this era.
While there is evenly distributed aging throughout, it retains an excellent overall atmosphere. For an early waterproof case with a black multi-scale dial, it represents a particularly attractive and well-valued example.
