Re: COSC Importance
In Response To: COSC Importance ()

: Am I wrong?

No, just confused. You watch should have come with a credit-card sized document stating it is a Chronometer.

The FULL certificate *is* the results of the test run on the actual movement that is installed in your watch.

But I was the one that compatred it to the Inspected By tag. In truth, COSC is merely another quality test run on the watch. If it failed, the movement would have been scrapped or repaired until it passed.

COSC really is a pretty nominal test anyway, it was created DECADES ago before modern mass production inproved overall quality and consistency so that virtually all watch movements made could easily pass. So it is really more of a marketing gimic to have the test done than it is any true measure of performance by modern standards.

Also understand that EVERY Omega CHRONOMETER watch has passed the same test as yours. So you have nothing to gain -- except very superficial curiousity value -- from seeing a piece of paper that tells you what you already know: that your watch passed the test.

If nobody told you there was such a thing as a Chronometer Certificate, you would have gone happily though life without it. But once people know that something like that exists, there is an odd compulsion to see it -- whether it means diddly or not.

But it means nothing and really is not worth the effort to bother anybody to get it.
