3s Upgrade Edition [Celebration] Omega/OMEGA Model 123.15.27.60.55.004. The fourth-generation Constellation, an eternal classic! This Constellation series features a smooth case and bracelet. This hard-to-find genuine Omega is available through a very reliable internal channel. Such quality items are not always available. If you like it, act quickly. This Constellation quartz diamond ladies’ watch has a diameter of 27mm. It is equipped with the original Omega 2800.01 movement, named Cal.1376 quartz movement. It has an anti-glare sapphire crystal. The watch is made entirely of 316L steel without electroplating, ensuring it will never fade. The butterfly clasp with the Omega logo is crafted from 18K gold. It comes with a certificate from the Chinese GTC testing institution. The bracelet’s inner text is composed of three different sizes and styles of fonts, which are clear and exquisitely crafted. It is not like the market versions with a single font running continuously. The Roman numeral markers on the black dial are genuine diamonds, making it luxurious and elegant. The central pattern and stars on the back cover are formed by oil pressure, with fine and full textures that are clear and distinct. Most importantly, each watch has a unique three-code combination.
