Accutron movement holder add-on

[LittleWatchShop]

I have a couple of these movement holders for 218 Accutrons.  In order to mount the movement, the holder must be splayed ever so slightly and then released when the movement is in place.  I have been splaying with a screwdriver, but this morning, I made an add-on tool that does the work for me.

I turned a slight conical profile with the initial diameter equal to the hole in the holder in rest position.  I turned to a larger diameter enough to open the holder enough for the movement to drop in.  Then I tapped the small end and made a threaded button.  The tool is mounted in the holder in a semi-permanent way.

When you want to insert the movement, press the pin from the inside of the holder and it splays out.  Once the movement is inserted, the outside butt is pressed so that the holder collapses on the movement.

I made two of these.  One is mounted on the holder with a brass button.  The other I show sitting alone so that the structure is obvious.

The second one uses the brass button--easier to turn and thread.
