Gents,
Just realized on Bremont's site all core watches are now tested to ISO 3159 standard. I know COSC certification also follow the ISO 3159 standard so I am wondering if there is any differences.
Does it mean starting from 2019 any new timepieces will not have a COSC certificate but will come with ISO 3159 certificate instead? If so who is doing the testing or issuing this new certificate?
Just wondering...
Thanks guys!
