Manufactured in the late 1950s, this Omega Seamaster Ref. 2990-1 is a rare example featuring the distinctive Ranchero-style case. Housed in a slim snap-back waterproof case that shares the same water-resistant construction as the iconic Omega Ranchero—one of Omega’s most celebrated models of the 1950s—it is powered by Omega’s legendary 30mm caliber, the Cal. 267.
The dial is of particularly high quality, featuring elaborately crafted embossed bullet-shaped hour markers with multiple faceted surfaces, paired with elegant dolphin hands. The substantial thickness of the applied indexes further enhances the dial’s striking presence, giving the watch a bold and highly distinctive appearance.
Bearing the reference number “2990-1,” this uncommon configuration is a rare find among Seamaster models of the period, making it a particularly desirable and collectible example.
