Why no 3 (crown) up position in the COSC chronometer test?
By: Marcus Hanke : March 22nd, 2018-06:00
I am a bit puzzled why the COSC chronometric test does not include the crown up position of the watch. Imho, testing all six position would only add another two days for the test, this should not cause too much additional cost. As a consequence, I have th...

Crown Up
By: chippyfly : March 22nd, 2018-06:29
I do not understand why either. 3-up would be an important position for a watch worn on the right wrist of a left-handed person ie where arm down for walking etc is one of the three major positions for timing a watch. I have a new watch on day 12 of my am...
I consider COSC chronometric tests ...

More a fad than a real test, since it's a movement only test. I saw, many times, a movement perform perfectly outside the case and, when cased, present totally different results. I hear, from several watchmakers that works on manufactures, that the moveme...
Hhmmm ... my view is somewhat different

I accept that the COSC tests have certain flaws, but also specific strengths: 1) they are a transparent and fully published standard. All testing procedures are known, all limits are known. So many watch manufacturers are busy criticizing the COSC, claimi...

COSC test is useless? I know brands that, despite the well know flaws of COSC, continue to certify their movements just to be able to write "Chronometer" on the dial. Did you know that is required to be COSC certified to write "Chronometer" on the watch? ...
Years ago I analysed COSC versus MC1000
By: Velociphile - No longer in the building : March 23rd, 2018-06:46
And published the results. It’s on the Purists somewhere and my own defunct blog. I will endeavour to find it and share again. Note that The JLC process is 1000 hrs not 100. In summary a watch that passes JLC MC1000 will likely pass the COSC but it is not...
It could be very interesting if you can do ...

A COSC x METAS (Omega Master Chronometer, that also includes COSC). They do 6 positions of a fully assembled watch, in addition to magnetic (15000 Gauss) and other torments. Cheers, Nilo
Since you are in Europe ...

I can try to book to you a visit to the Omega/Metas certification lab. It will be a great comparison. COSC x 1000 hours x METAS. PM me if you are interested. Cheers, Nilo

This could be an exam question before you're allowed to apply for a Rolex Steel Sports.

Since years, I somehow felt convinced that 3 up was not included. I have no idea why this misunderstanding could develop. Of course I withdraw my question, offering my apologies for wasting your time. But since we are at it: Why should it be a good reason...
