A true collector’s gem from the golden age of chronographs — the Omega Chronograph Cal. 320 Jumbo in 18k rose gold.

Introduced in the 1940s, the legendary Omega Caliber 320 is celebrated for its precision, durability, and elegant construction. Produced in relatively small numbers, watches powered by this movement are today regarded as highly desirable collector’s pieces.

This exceptional example stands out with its impressive 37.5 mm jumbo rose gold case, crisp beveled lugs, and beautifully preserved details. The rose gold syringe hands and hour markers add warmth and balance to the refined dial layout.

Preserved in what we confidently call flawless condition, this is a once-in-a-generation find — rarely seen, and even more rarely offered.
