The signed crown has significant damage and chipping along its outer edge. In contrast, the dial and hands remain exceptionally clean and well-preserved, free of notable aging. Supported by the 6-10s/day timegrapher reading, the movement is performing with impressive consistency. Dimensions The case size is 36 mm (excluding the crown). Remarks This Constellation offers a compelling contrast between its honestly worn exterior and its exceptionally preserved dial. The presence of the chronometer-certified Caliber 751 and the original integrated bracelet make this a highly authentic and appealing example of 1970s Omega design. History During the late 1960s and early 1970s, the Constellation collection shifted towards architectural case designs with integrated aesthetics. This evolution reflected the changing tastes of the era, moving away from traditional curved lugs toward more substantial, geometric profiles. This specific example represents that transitional period perfectly, housing the highly respected Caliber 751 movement within a beautifully integrated stainless steel form.
