Agreed.

Without one how do you know how well that new expensive new watch is actually running, even if it seems to be keeping good time ? Relying on the manufacturer's marketing assurances that it must be fine ? Note that most (if any ?) don't give you the COSC certificate or even their own timing results.

The OP's example is a good one - accuracy seemed to be reasonably OK without being outstanding, and several contributors telling him that there was no problem with it - but in reality it was pants once you took a close look at how it was running.

Ditto that expensive service you had done that promises to return a watch to ex-factory condition. I've sent a couple of watches back because they clearly weren't.

You have to wonder how many folk without one of these get sub-standard products or service without ever knowing.
