Doesn’t anyone ever heard of a time grapher ?and regulating a watch?

Every watch i buy, immediately undergoes vigorous regulating to at least +1 sec/day…

It takes a few days of trial and error.. but it worth it. An accurate mechanical watch is better than any beautiful and not accurate one.. watch is supposed to be accurate..

Btw, thats why swiss movements are superior to everything else (except spring drive..)
