: I cannot answer as to why it is not COSC certified but to be honest
: I think a lot of people get hung up about that anyway. Unless
: your job or serious hobby I.e. Motor racing or flying requires
: that range of accuracy ....

The COSC does not make a watch accurate or more accurate. It is only a certification of how a sample of watches submitted by a company performed. It does not mean that an non-certified necessarily watch performs better or worse. It is something a company can choose to pay for or not.

As was said, if your job requires a COSC certified watch then I guess it should matter. I do not know of any job which requires such a thing these days since we all have much more accurate time keeping devices in our phones.
