Mike,
This survey is fraught with problems.
One: there is no denominator.
Two: there is no criterium for quality or independence.
Independent assembly vs Independent manu- facture?
Even if hand crafted....done well by a meister or cobbled together by a well-meaning primate?
Do you need photo evidence of model names as likely few people know many of the makers, let alone model names?
Maybe confined to AHCI circle only, to keep it topical to the launch today of that initiative?
At least two watchmakers on your spreadsheet are not "independent"......
Regards,
MTF
