History Throughout the mid-20th century, Omega dedicated substantial resources to crafting elegant, high-precision timepieces for women. Unlike many brands that relied on third-party movements for their smaller watches, Omega developed dedicated, in-house miniature calibers like the 484 to ensure their ladies' collections met the same exacting chronometric standards as their men's lines. Watches like this reference 511.166 reflect an era when mechanical sophistication and delicate, jewelry-inspired design were seamlessly integrated. / Second Vintage SKU: OME-OXX-0027
