Vintage Omega Constellation Chronometer Electronic F300Hz D-Shape S.F. 198.0004 - 40mm - 1972

A Vintage Omega Constellation D-shape produced in 1972, featuring a highly unusual vertically asymmetrical tonneau-shaped case design with its original integrated bracelet made specifically for this reference. This watch remains entirely original and preserved in exceptional condition, with the full original polish still beautifully intact, showcasing the combination of brushed surfaces alongside sharp high polish edges and bezel finishes exactly as intended by Omega. The striking blue dial pairs perfectly with the futuristic case design, while inside sits the Omega caliber 1250 quartz electronic F300 hertz movement, which we had serviced in May 2026 and now runs and functions excellently. The bracelet is fully linked and sizable up to approximately 20.5cm wrist circumference. Even the caseback still shows remains of the original purple factory sticker, further highlighting how remarkably well preserved this example truly is. Overall, this is without question a true collector’s piece and an exceptional example of Omega’s innovative early 1970s design language.
