This is the eyepiece of an Omega Seamaster watch, made of black silicone with a metal bezel. Even under high magnification, minute scratches on the lens are clearly visible. Suitable for watch repair and jewelry appraisal. The description should end with this sentence: "These products are 'authorized' goods, typically used by suppliers as promotional gifts at trade shows. Authorized goods are not manufactured or sold under the brand name they are advertised as. Labels such as 'authentic' or 'original' do not apply to distributors' products."
