Thank you for viewing. This is a rubber strap that can be used for Omega Speedmaster and Swatch Omega watches. It says Speedmaster and looks cool. It has a push-button deployment buckle. The band end has a curved shape, so it fits the curve of the watch. Please understand that this is not a genuine product, but an aftermarket one.
