1958 Omega Seamaster 2975-1

The 1958 Omega Seamaster ref. 2975-1 is a beautifully preserved example of Omega's golden era. Housed in a 35mm stainless steel case, it features the highly sought-after "Big Logo" Seahorse caseback—a rare detail that makes this reference especially desirable among collectors.

Its striking midnight black dial delivers timeless elegance with unmistakable vintage character, while the premium brown leather strap provides a refined finishing touch. Beneath the dial beats the reliable automatic Omega Calibre 501, celebrated for its smooth performance and enduring quality.

Presented in its original Omega box, this Seamaster is a superb blend of heritage, craftsmanship, and everyday wearability—an exceptional addition to any vintage watch collection.
