Just wondering why a low beat 6497 has a nicer Swan Neck Srew (may not be gen like ) as compared to a better high beat clone 6497 movement.
Also are they the same fit?
high beat is not always 'better' than low beat. They're different movements using different gear trains, thats the only difference. The swan necks are totally interchangable.
The reason for the difference is due to the factories that make these.
