I need to spend extra time speaking about the dial structure of this watch, but Permit’s 1st mention the motion. Inside the Speedmaster Chronoscope would be the Co-Axial Grasp Chronometer Omega caliber 9908 manually wound chronograph motion. Set only, it is a minimalized version of Omega’s equivalent automatic chronograph motion https://www.watchesworld.com/frozen-in-time-luxury-watches-for-winter/
