History During the mid-century era, Omega produced a wide variety of elegant dress watches characterized by refined proportions and understated designs. The manual-winding caliber 620 was a reliable and widely respected movement in the brand's catalog, frequently utilized to achieve the slimmer profiles desired in formal timepieces of the 1960s and 1970s. These classic models continue to be appreciated for their handsome style and reliable mechanical performance. / Second Vintage SKU: OME-OXX-0020
