There has been fairly constant referrals and comments on winding/over winding issues with
certain ETA/Sellita calibers particularly the widely used 2824 series.
Is this due to metallurgy, wheel design-tooth irregularities-or overall movement design? (Not lack of maintenance.)
This is an issue begging for educated horologists/watchmakers studied answers-not just a variety of forum opinions.
Your input is respectfully solicited.
