Brand: Omega Model: Constellation Reference Number: 157.0001 Serial Number: 35903165 Movement: Automatic Caliber 712 Dial: Silver sunburst dial with applied black baton indices, exceptionally clean with minimal signs of aging Case Size: 34 mm (excluding the crown) Case Material: Stainless steel Production Year: 1972 Condition: Excellent vintage condition with a beautifully preserved dial and honest case wear Dial and Hands The dial is a masterclass in minimalist mid-century design, featuring a brilliant silver finish with a subtle, radiant sunburst texture that captures the light beautifully. It is adorned with applied black baton hour markers that provide striking contrast and excellent legibility. The typography is crisp and intact, featuring the applied Omega logo, the elegant "Constellation" script, and the "OMEGA CHRONOMETER AUTOMATIC" designation clearly printed above the six o'clock position, just above the "SWISS MADE" signature. The original thin black stick hands perfectly match the indices, completing the two-hand dress configuration. Condition-wise, the dial is remarkably well-preserved, remaining incredibly clean and free of any distracting spots, moisture stains, or significant patina, presenting a highly attractive and fresh appearance under close inspection. Case and Crystal The 34-millimeter stainless steel case is distinguished by its ultra-thin profile, allowing the watch to slip effortlessly under a tailored shirt cuff. The case features a smooth, minimalist bezel and elegantly curved short lugs that hug the wrist perfectly. The winding crown is properly signed with the Omega logo. Turning the watch over reveals the iconic Constellation snap-on caseback, proudly displaying the Observatory medallion with its eight stars in crisp relief. Inside the caseback, the reference 157.0001 and traditional Omega hallmarks are clearly stamped. The exterior case remains in very good vintage condition, exhibiting honest, superficial handling marks and light scratches consistent with careful wear over the decades, while retaining strong overall geometry. As is common with vintage snap-back cases, there is some visible pitting and grime accumulation along the hidden inner lip of the case, which is entirely concealed when the watch is closed. The crystal is clear and well-preserved, offering an unobstructed view of the stunning dial. Movement Powering this elegant timepiece is the copper-finished Omega Caliber 712, renowned as one of the brand's thinnest automatic movements. The visual inspection of the movement reveals a beautifully preserved mechanism with its original factory finishing intact. It is proudly engraved with its 24-jewel count and notes its chronometer-grade adjustment to five positions and temperature. The serial number 35903165 is clearly visible on the bridge, dating the watch to the early 1970s. Exhibiting remarkable accuracy and consistency, performing brilliantly for a vintage timepiece. The timegrapher indicates a highly precise rate of -12 to -14 seconds per day with strong amplitude. Strap The watch is fitted with a handsome dark brown leather strap featuring vintage-style contrast stitching at the lugs and buckle. This period-appropriate strap complements the silver dial and stainless steel case perfectly, offering a comfortable and stylish wear experience. Condition This Constellation survives in excellent vintage condition, standing out primarily due to its exceptionally crisp and clean dial. The stainless steel case has aged gracefully, showing normal signs of use while preserving its slim, elegant lines and the all-important Observatory medallion on the caseback. The movement is clean and running with impressive precision. It is a highly attractive and honest example of a sophisticated vintage Omega. Dimensions The stainless steel case measures a classic 34 mm in diameter, excluding the original signed crown. Its defining feature is its remarkably slender profile, providing a refined and unobtrusive presence on the wrist that is characteristic of the finest vintage dress watches. Remarks Omega Constellations powered by the Caliber 712 are highly sought after by collectors who value the intersection of chronometer-level mechanical sophistication and ultra-thin dress watch design. The absence of a sweeping seconds hand gives this specific reference a serene, uncluttered aesthetic that feels incredibly modern while remaining firmly rooted in classic 1970s elegance. History Introduced in 1952, the Constellation was designed to be Omega's flagship line, representing the absolute pinnacle of their chronometer-certified production. The line was distinguished by the Observatory of Geneva medallion on the caseback, surrounded by eight stars representing Omega's numerous precision records set at observatory trials in the mid-20th century. Over the decades, the Constellation evolved from the pie-pan dials of the 1950s into the sleek, ultra-thin dress models of the late 1960s and 1970s, continually pushing the boundaries of elegant case design and mechanical reliability.
