Dial and Hands
The vertically brushed champagne dial is a standout feature, catching the light beautifully and remaining in exceptionally clean condition with no visible spots, moisture marks, or blemishes. It features applied gold-tone baton indices with black inlays that perfectly match the sleek baton hands. The applied Omega logo at twelve o'clock adds dimensional depth, while the classic typography for "OMEGA AUTOMATIC" and the script "Seamaster" remains crisp and fully intact. A framed date aperture sits cleanly at the three o'clock position, and the "SWISS MADE" designation is clearly printed at the bottom edge.

Case and Crystal
The 35mm tonneau-shaped case features a 20-micron gold plating, paired with a stainless steel caseback. The case exhibits honest signs of vintage wear, with visible plating loss and brassing along the sharpest edges, particularly on the lug hoods and case flanks, which is consistent with regular use over the decades. The Omega-signed crown is present and well-defined. The domed acrylic crystal protects the dial and shows only light superficial wear, maintaining excellent clarity. The stainless steel caseback features a crisp and deep engraving of the iconic Seamaster Hippocampus medallion.

Movement
Inside beats the Omega caliber 1012, a robust automatic movement featuring 23 jewels. The characteristic copper-toned plating of the movement is bright and well-preserved, with clear engravings of the caliber number, jewel count, and the serial number 40536152, which dates the watch to approximately 1977. Performing well within expected vintage tolerances; running strong and steady. The timegrapher results indicate a performance of +29 to +33 seconds per day.

Strap
The watch is fitted with a modern black leather strap featuring distinctive grey and yellow-gold contrast stitching that complements the dial and case tones. It is secured with a gold-tone pin buckle.

Condition
This Omega Seamaster is presented in good vintage condition. The dial is stunningly preserved, standing in contrast to the case, which shows expected and honest plating wear along the edges. The movement is clean, well-preserved, and fully operational.

Remarks
This Seamaster is a highly wearable vintage piece that perfectly captures the aesthetic of late-1970s Omega design. The striking contrast between the textured dial and the stylized cushion case makes it an excellent choice for both seasoned collectors and those new to vintage watches.

History
The Omega Seamaster line, introduced in 1948, was originally designed as a robust, water-resistant watch for active individuals. By the 1970s, the collection had expanded to include a wide variety of case shapes and dial designs, reflecting the bold styling trends of the decade. The cushion-cased models from this era are particularly appreciated for their substantial wrist presence while maintaining the sophisticated engineering Omega is known for worldwide.
