Hi tritto,

ALL calibre 4006 Bell-Matic models share the 325T02AN crystal. The only Bell-Matic models that do use a different crystal (325T04AN) are the rare calibre 4005 date-only watches.

The SK crystals as mentioned by Mike have a different profile and sometimes are hard to fit, but should do the job. If the tension ring is ok, you could also purchase a NOS one with a gold ring and swap it with the one you have currently installed in your Belle.

Good luck and let us know how it turns out :)
