Thanks for your reply.
The 6mm crown actually fell apart. I have a new 21j Asian that runs well and is accurate. The crown can't be repaired the tube that screws onto the stem broke off the crown.
I have the proper tap 10 stem and need a standard ss rep crown.
Perhaps someone has one out there there has one or I will have to obtain a generic.
Most likely a TD would not be bothered with such small item, unless I placed a watch order.
Any advice where I might obtain one would be appreciated.
THANKS
