Extra o ring / gasket DWC-D02S: where does it go, is it for the crown?

DIY Help

Hi, watch has been assembled and everything works well.
I notice that there is an extra o ring at the end. Is it meant to go anywhere?

Someone i know suggested the stem of the screw down crown. Any pictures on where it should go? I did not seem to see an o ring on the stem in the videos.

Link here for the small o ring

Thank you!!

That looks like the o ring inside the crown. Not on the stem but inside the crown.

Thanks! I also thought so initially. Anyway it seemed too big. I emailed DIYwatchclub and basically it was the o ring for the loupe holder :rofl:
