This is a 1949 Omega caliber 351 bumper automatic winding movement. These bumper movements were amongst the first automatic winding Omega watches. This movement was recently cleaned and is accurate. The gold-filled 32.3mm case looks excellent and retains the correct Omega winding crown. The pristine silver dial print was restored and retains the original raised gold-toned arrow markers and Dauphine hands along with the Breguet numeral 12. The Dauphine hands and blued steel sweep seconds are original.
