And today even a Rolex movement is highly robotised automated and mass produced.

I think the cosc test is mostly a marketing gimmick. IWC, Patek, Panerai, just to name a few big names, aren't "certified chronometers". IWC has stricter criteria as I'm sure Patek does as well.

Dont forget the COSC spec is a AVERAGE of between -4 to + 6 seconds over any 24 hour period.

Bought it brand new from my AD last May. Brought it home and set it spot on with the Atomic Clock. Today over a year later - wearing it everyday through a back country lifestyle.....it has remained between +15-20 seconds fast - over that entire period. I have never reset it - it has never stopped. For hour changing this movement rocks since only the hour moves when needed.

Update: a half hour later, I'm still on the money.lol

Another update: Sept 3rd, 2:45 pm. Since Sept 1st at 9:15pm, my watch has lost about 8-9 seconds. I'm fine with it as it is.
