This Constellation series watch features a polished case and strap, and this model is a solid piece, sourced through very reliable internal channels. A limited number of original Omega watches have been reserved by the factory! Good items aren't always available, so act fast if you're interested. This Constellation series quartz diamond ladies' watch has a diameter of 27mm and is equipped with the original Omega Caliber 2800.01 quartz movement, named Cal1376. It features an anti-reflective sapphire crystal. The watch is made entirely of 316L stainless steel, free from electroplating, ensuring it never fades. The butterfly clasp logo is crafted from 18K gold and comes with a certificate from the China GTC testing institution. Additionally, the strap's head particles are distinctly different from the market version. Note that the internal strap text consists of three different font sizes, clearly crafted, unlike the market's standard font. The watch face features a radiant black dial with genuine diamond hour markers, exuding luxury and elegance. The back cover's central pattern and the stars are finely detailed with oil-pressure molded textures, showcasing a rich and clear three-dimensional feel with two levels of concavity. Each watch is uniquely numbered with a three-code combination. This is the best luxurious gift recommendation; trust only the exclusive quality of 3s.
