Bulova case back wrench 9082

You should be able to open it with a jaxa wrench James.

If this is one of those octagonal cases, it does have a specific case opener, but they are difficult to find.

There is an horological 'ball' type opener, which works by friction and cannot mar the metal of the case. It's an inflatable ball and is surprisingly effective.

Thank you both for your suggestions.

Oddly I found that my crystal compresser works great.

ALSO

Does anyone know if the 10CNCH is the only true 24 hour movement Bulova made?

Also is it possible someone knows what Bulova called the watch.?

Thanks

James
