Part of the legendary Omega Speedmaster collection, the Mark II Co-Axial chronograph watch has a matt black dial protected by scratch resistant sapphire crystal. The three chronograph sub-dials sit perfectly at the 3, 6 and 9 o’clock indices. The transparent tachymeter scale on the crystal is illuminated from beneath by an aluminium ring filled with Super-Luminova. All encompassed in the 42.4mm brushed stainless steel case and matching bracelet and powered by the exclusive Omega Co-Axial calibre 3330 Swiss movement.
