Vintage Omega Seamaster “Fat Lugs” Swiss Watch, Cal. 501, Two-Tone Salmon Patina Dial from 1956
Here is a 1956 Omega Seamaster that stands out immediately for its presence on the wrist: the celebrated “fat lugs” case paired with a warm two-tone dial that has developed a striking salmon patina. This combination has become highly sought after in the vintage Seamaster world, especially among collectors who appreciate dials that age with character and individuality.
The dial is the key feature. Its soft, even salmon coloration sits inside a contrasting outer ring, creating a subtle two-tone effect that feels unmistakably mid-century. The patina shows delicate spotting and gentle aging, giving the watch a lived-in charm without compromising its readability. Applied Arabic numerals at the cardinal points and dagger markers complete the classic Omega layout, while the golden “Seamaster” script adds a refined finishing touch.
The 34mm stainless steel case wears a bit larger than the number suggests thanks to the broad, sharply defined lugs—hence the “fat lugs” nickname. On the wrist, the proportions feel solid yet understated, making this Seamaster an easy companion for both casual and more formal settings.
Below the caseback sits Omega’s Caliber 501, part of the brand’s early high-grade automatic movement family. The serial number 15348225 dates the watch to 1956, placing it squarely in the early evolution of the Seamaster line, when Omega was refining the design that would eventually become one of its most enduring collections.
