Thanks for your writeup!
Fascinating to see how much testing goes into a Grand Seiko! From your visits to other manufacturers, were there any other notable qualities of the certifications or testing processes across brands? I'm particularly interested in better understanding the differences (if any) across the finishing-based certifications.
Thoughts on certifications?
I'm curious what the general opinions on certifications are aside from COSC. Geneva seal, Patek seal, Qualite Fleurier, JLC 1000 hours, etc...Who's got the most stringent? Do they differ in any interesting ways? Or are they all just BS? added image for in...
What I like about COSC—and Omega’s METAS—testing is that they refer to a quantitative performance metric that’s highly relevant to me: the watch’s ability to keep accurate time.
The other metrics are concerned with levels of finishing (Geneva seal) or general functionality (JLC 1000 hrs). So they really all mean very different things.
Agree that chronometry certifications are generally useful
I'm quite surprised that so many high end watches come with no accuracy specifications whatsoever. Especially ones with chronometry complications like torbillons.
Certifications are intended to demonstrate facts...
...and not judgments. They mean that the thing being certified has been specifically verified to be true by the certifier. As such, evidence is required to support the fact. Thus, “our watches are great because we are great” certifications are rather vacu...
Testing to the Grand Seiko standard
I have been to a number of Swiss workshops including V-C, JLC, BP, PP, Fleurier, etc. Everyone tests their watches to some degree - though JLC explains their Master Control 1000 hr test as one of the best. I have the best pictures to share with you from m...
