3s Production 3s Upgrade Version Omega/Omega OM3 Model 123.15.27.60.55.004. Fourth Generation Constellation Eternal Classic! The Constellation series features a polished case and strap. This hard-to-find item comes from a very reliable internal channel, with only a limited number of original Omega watches reserved by the manufacturer! Good things are not always available, so if you're interested, act quickly. This Constellation series quartz diamond women's watch has a diameter of 27mm and is equipped with the original Omega movement model 2800.01, named Cal 1376 quartz movement. It features an anti-reflective sapphire crystal. The entire watch is made of 316L stainless steel with no electroplating, ensuring it never fades. The butterfly clasp logo is crafted from 18K gold. It holds a certification from the China GTC testing agency, and the strap's head particles are definitely not the protruding versions found in the market. Note that the internal font of the strap consists of three different sizes and styles, with clear lettering and exquisite craftsmanship, unlike the single continuous font commonly seen in the market. The Roman numeral markers on the black dial are adorned with genuine diamond inlays, exuding luxury and elegance. The central pattern on the case back and the stars feature finely detailed oil-pressed textures, providing a strong three-dimensional feel with two levels of concavity. Additionally, each watch has a unique three-in-one independent code. It is the best luxurious gift recommendation. Please recognize the exclusive quality of 3s.
