Does cosc mean anything in a quartz watch?? I mean the variance tolerance should already be low, not like an auto

Well, for quartz watches it's just a matter of certification. Most quartz watches with a decent movement would meet COSC standards for accuracy certification. However, manufacturers don't really bother themselves with getting the certification as each and every watch has to be sent in for certification. Also, COSC standards include other factors like water resistance and temperature resistance, not just accuracy.

It's NOT a powermatic 80 movement which is an automatic ETA movement, it is a quartz ETA movement.

If this was the powermatic movement it would be a screaming deal, but it is a warm one for quartz, even with COSC.

Here you go: https://www.cosc.swiss/en/certifi...-movements

Any quartz watch should be pretty accurate, but that can vary with temperature and humidity. A certified quartz watch will be "thermocompensated," which corrects for that.

I'm not all that interested in them; I have a cell phone to tell me the correct time. To me, an automatic watch is more like a cool little machine, like a model steam engine is.

It does mean that a shady seller (which Joma is) wants to hide the price of previously sold pieces that were listed on the same page.

COSC has different (much stricter) requirements for quartz movements.

Downvoted until OP corrects posting to show that this is the PR100 Quartz COSC, not the PR100 Powermatic 80 COSC.

COSC is just about the movement. A company sends only the movement to be tested for accuracy, they don't send the whole watch. No water resistant tests, temperature yes because that has a factor in it's accuracy
