This is a large-sized 35mm very early bumper automatic winding watch dating to 1943. This is amongst the very first of the automatic winding Omegas. The Omega bumper automatic winding movement was just cleaned and is keeping time accurately. The dial was restored many years ago and retains the original hands. This watch has an all-dial appearance, making it appear larger on the wrist. These early watches did not have signed Omega crowns.
