The OMEGA Speedmaster Chronoscope 329.33.43.51.02.001 is crafted in a 43mm stainless case and styled on a blue leather strap. The silvery dial hosts blue accents in the hour markers, hands, surrounded by a blue inner bezel ring with Tachymeter functionality. Three timing scales on the face of the dial feature a unique snail design that pays homage to Omega watches from the 1940's. An exhibition case back provides a unique view of the complicated movement that powers this timepiece.
