Housed in a 31mm round stainless steel case, this Omega Constellation presents a black dial protected by an anti-reflective, scratch-resistant sapphire crystal. A fixed bezel frames the dial, while a transparent case back offers a view of the movement within. Water resistance is rated to 100m/330ft, and the crown is not of the screw-in variety.
Power comes from a Co-Axial automatic movement that carries COSC chronometer certification, denoting independently verified precision. The brushed stainless steel bracelet is fitted with a push-button folding clasp for secure and convenient wear.
Reference 123.10.31.20.01.001 is listed in new/unworn condition, making it a compelling choice for those seeking a classically proportioned Constellation in stainless steel.
