I've 'infected' a work colleague with the tinkering bug, so he bought this movement as the basis for a project.

However, he is strugling to identify a suitable case
On some sites parts seem to be suited to several other Miyota movements 8215 8205 8217 etc...

Is the 8n24 just a skeletonised version of another movement - if so which one ?
...or are there other differences in diameter / height etc ?

Any advice / pointers on where to get a case much appreciated.

TIA
