Assistance Needed: Crown and probably Stem Replacement for Aqua Terra 2503.30

Dear Friends,

I hope you’re all doing well.

I’m reaching out for some help with my Aqua Terra (Ref. 2503.30, 39mm). I need to replace the crown and any associated parts, as I suspect the threads on the stem or in the crown might be damaged. Currently, the crown does not screw in completely.

If anyone could assist in finding the reference numbers of this parts or even sourcing these parts—whether new or in good used condition—I would greatly appreciate it. Any advice or guidance on resolving this issue would also be very welcome!

Thank you in advance for your time and support.

Best regards,
Panos

Dear @Archer

Apologies for bothering you again, but I’ve been told that the ETA 2892-401 winding stem is the same as 72211205101021. Could you please confirm if this is correct?

Thank you so much for your time and help!

You are great !
