hard enough to find like this where's the movement first kind of automatic movement has ever made by Omega, now we known as bumper movement, why it called like that cause rotor can not spin 360 degrees, only bump and then back to other side vice versa to fulfil power reserved
if we look backcase without O-ring gasket it means first generation of calibre 351 so on the dial has no collection series name like speedmaster, seamaster, geneve etc., on the dial only has Omega symbol and then under it has typed OMEGA, and then AUTOMATIC, under six gold marker has tiny typed "swiss made", we can read all typed with clearly
with gold sweep second hand and gold hands same with gold markers on the white satin dial, all parts are still genuine : solid 14k goldtop case, without O-ring gasket backcase, goldtop crown (starfruit type), and then the last but not least is genuine with tiny Omega symbol at the center armoured hesalite crystal made it looks so beautiful antique Omega wirstwatch
