Brand: Omega Model: Seamaster Cosmic Reference Number: 136017 Movement: Automatic Dial: Silver sunburst with black applied indices, framed day and date window, and creamy tritium lume pips; exceptionally clean condition Case Size: 35 mm (excluding the crown) Case Material: Stainless steel Production Year: 1970 Condition: Excellent vintage condition with an exceptionally preserved dial Dial and Hands The dial of this Seamaster Cosmic is a visual delight, featuring a pristine silver sunburst finish that radiates beautifully under the light. It is exceptionally well-preserved, showing virtually no signs of spotting, moisture damage, or unwanted discoloration. The dial architecture is defined by striking black applied square indices that provide excellent contrast and depth. An outer grey track with crisp white minute markers frames the dial perfectly. The original tritium lume pips, positioned just outside the indices, have aged to a warm, creamy pumpkin tone, matching the luminous material present in the black baton hands. A framed day and date aperture sits cleanly at the three o'clock position. The typography, including the applied Omega logo and the distinctive Seamaster Cosmic script, remains factory crisp and fully intact, while the bottom edge proudly bears the T SWISS MADE T designation.

The case remains in excellent vintage condition, retaining sharp factory lines and a beautiful contrast between the vertically brushed top surfaces and the highly polished case flanks. Honest, light handling marks are present, consistent with careful vintage wear, but the case shows no signs of heavy polishing or significant trauma. The original Omega signed crown, featuring the iconic horseshoe logo, is present and easily operable. A domed acrylic crystal protects the dial, presenting clearly with only faint micro-abrasions that do not detract from the stunning dial beneath. The brushed solid caseback is remarkably clean, completing the well-preserved nature of this timepiece. Movement This Seamaster Cosmic is powered by a robust Omega automatic movement, securely housed within the front-loading unishell case. While the movement is not pictured due to the solid one-piece case construction, it functions as a reliable engine for the day and date complications.

The strap is secured with a classic stainless steel pin buckle, providing a comfortable and secure fit on the wrist while perfectly complementing the monochromatic aesthetic of the dial and case.

The dial is the undeniable star of this piece, remaining remarkably clean and free of the spotting or degradation often found in watches of this vintage. The hands and indices are pristine, and the tritium luminous material has developed a highly attractive and even patina.
