I guess opening a new thread won't get you any closer to the answer, and will be very confusing for those who will look for the answer to this question after you and stumble upon this.
I believe the moderator will ask you not to create more than one topic per question, however, I can only warn you against this, and once again advise:
- You can try to contact Prof. He works with crystals, but I don't know if he makes them.
- @Etshazam is the only one who offered them for purchase.
- Some members such as
Karlchen do it for their watches locally.
There are no other options for solving this problem in the broad masses. VSF made some SUBS (eg 389) in some periods with the right crystal, but this is no longer the case.
