Slipping when winding

[mysterio]

hmy: i knew the crown is not right it can't be that wobble and loose for a crown. Is there any way to fix it or should i replace it @mysterio ? sadly with the QC pics i can't tell is the crown wobbly or not but i did ask the QC personnel to do me a favor and check the crown and movement, he didn't reply my question it will be hell to send it back again ~_~

For the winding matter i asked, i wound the watch 50 times and it has been running since yesterday with no gain or loss or time, i've been monitoring it with my other watch and phone time, it's the same. I'm able to wind the watch but the crown is very wobbly.

That means your only remaining issue is the wobbly crown. I have not encountered a wobbly crown before so I have not tightened a crown as well but a watchmaker should make this an easy job. If you're handy with watch repairs, you could do this yourself as well. The process involves removing the stem from the movement before tightening the crown on the stem which is locked on a pin vise. You can't tighten the crown whilst the stem is inserted in the movement because the spring will always push back when it's tightly wound and like I said to tighten any further may possibly break the spring. So you need the stem on a firm unmoving base, which is the pin vise.

Remove stem from A6497 movement:
At 11:35

Replacing crown on winder stem (well you won't be replacing the crown, but you'll see the pin vise and how to unscrew [counter clockwise] the crown. Tightening is just the other way [clockwise])
