Omega Seamaster Automatic Day Date - 166.021

The Omega Seamaster Automatic Day-Date ref. 166.021 is a classic 1970s dress-sport watch, distinguished here by its striking black dial that adds depth and contrast to its vintage design. Housed in a stainless steel case, it features a softly rounded, cushion-shaped profile with integrated lugs, giving it a distinctly retro yet versatile presence on the wrist. It is powered by Omega’s reliable automatic Calibre 1020 movement and includes a practical day-date complication. The approximately 35–36mm case is fitted with an acrylic crystal, enhancing its warm, period-correct character, and is paired with a matching stainless steel bracelet—typically a flat-link or folded-link design—that sits seamlessly with the case for a cohesive, streamlined look. Altogether, the 166.021 offers a refined balance of everyday functionality, vintage charm, and unmistakable 1970s Omega styling.
