Omega Seamaster Chronograph Cal. 321 – Ref. 105.004 (1960s)

The vintage Omega Seamaster Chronograph Ref. 105.004 is a highly collectible example of mid-century Swiss chronograph design, powered by the legendary Caliber 321 movement. Produced in the 1960s, this reference represents a period when Omega was manufacturing some of its most respected mechanical chronographs—sharing the same base movement lineage as early Speedmaster models.

The watch features a classic round case with balanced proportions, typically measuring around 35–36mm, offering a timeless and highly wearable size. The dial showcases a traditional dual-register chronograph layout with clean symmetry, often complemented by tachymeter or telemeter scales depending on configuration. Vintage patina, when present, enhances the character and desirability of these pieces among collectors.

At the heart of the watch is the Omega Caliber 321, a column-wheel chronograph movement widely regarded as one of the finest ever produced. Known for its smooth actuation and historical significance, the Cal. 321 adds substantial collector appeal and long-term value to this reference.

With its blend of technical pedigree, elegant design, and historical importance, the Seamaster Chronograph 105.004 stands as a cornerstone piece for vintage Omega enthusiasts.
