Omega Seamaster 135.007-66 (1964)

Available now on auction by Second Vintage This is a quintessential example of mid-century Swiss horology, representing one of the most respected manual-wind models produced by Omega in the 1960s. The Seamaster 30 is highly regarded by collectors not for a 30-meter depth rating, as commonly mistaken, but for the famous 30mm diameter of its movement series, which was renowned for its precision and robustness. This specific example features a remarkably preserved sunburst dial and the legendary Caliber 286, offering a blend of dress-watch elegance and tool-watch durability that few other vintage pieces can match.

The watch presents beautifully with a sharp case and a dial that has been exceptionally well preserved. The movement is clean and running within vintage tolerances. Dial and Hands The silver dial features a fine sunburst finish that catches the light beautifully, creating a dynamic appearance on the wrist. It is adorned with applied silver baton indices and the applied Omega logo at the 12 o'clock position. The original dauphine hands show authentic aging consistent with the watch's vintage nature. Small luminous plots at the outer edge of the indices have aged to a warm, pumpkin-like patina, matching the lume on the hands. The dial is signed "T Swiss Made T" at the bottom, indicating the original presence of tritium. Case and Crystal The stainless steel case measures 35mm in diameter and retains strong, defined lines on the lugs, suggesting it has been treated with care over the decades. The polished surfaces show light surface wear typical of a watch of this age but remain very attractive. The signed Omega winding crown is present. The screw-down caseback features the iconic Hippocampus (seahorse) medallion, which is crisp and clearly visible. The inner caseback is stamped with the reference 135.007-66 and Omega hallmarks. Movement Powering this timepiece is the celebrated Omega Caliber 286, a 17-jewel manual wind movement with a copper-colored finish. This movement is part of the legendary "30mm" family, famous for its large balance wheel and stability. The serial number 21360425 dates the production of this movement to approximately 1964. The is running within vintage tolerances. Strap The watch is fitted with a black leather strap featuring white contrast stitching and a silver-tone buckle. The strap is in good condition, soft and ready to wear, complementing the monochromatic aesthetic of the silver dial and steel case. Condition This timepiece is in excellent vintage condition. The dial is free from significant spotting or damage, retaining a bright and clear finish. The case shows honest wear with minor scratches but no deep dings or signs of over-polishing. The crystal is clear, allowing for excellent visibility of the dial. Dimensions With a case diameter of 35mm excluding the crown, the watch sits classically on the wrist. The lug-to-lug length and slim profile of the manual-wind movement allow it to slide easily under a shirt cuff, making it an ideal dress or daily wear companion. Remarks The Seamaster 30 is often cited as one of the best value propositions in vintage collecting due to the high quality of the 30mm movement series. Finding an example with such a clean dial and a sharp caseback engraving is becoming increasingly difficult. History Introduced in 1948 to celebrate Omega's 100th anniversary, the Seamaster line was based on waterproof wristwatches made for the British Royal Navy during World War II. The Seamaster 30 specifically pays homage to the 30mm caliber, a movement architecture that dominated observatory precision competitions for years. This model serves as a bridge between the utilitarian roots of the brand and the elegant design language of the 1960s. / Second Vintage SKU: OME1K8RXPA000
