I need the gear that rotates the bezel ring on a 1970 super seawolf

[dfinitiv]

The gear on the rotating bezel at 11:00 stem position is broken off. Where can I find said gear, and a replacement crystal??

Are you talking about the SST Sea Wolf? I do not know of any gear on the SSW.

As long as you are willing to look there may always be hope, but I can tell you that will be an impossible part to find.  That is the part that always fails on dive watches with inner rotating bezels (although it is usually that they have seized up, not broken off), and they have long since been used up. 

As for the crystal, nearly as impossible.  That is an extremely large size for a ST type crystal, and I do not think that any of the current makers provide a crystal that large in the proper style.  The crystals made today will not have the thickness or same domed heigth that the original had either, the original is truly more of a DT type crystal, which I dont even know if they make at all anymore.  FYI, you will need to be able to use the original crystal trim ring for a proper look even if you can find a crystal large enough to fit.  You would be better off having the original crystal professionally polished by someone that knows what they are doing, if you have it that is.
