Here we have the 2023 version of the 407A tool, which can be used for repair of many calibers. It is designed to fit the movement perfectly without the need for adjustable holders that always slip. Additionally, it makes the alarm ring adjustment much simpler on the 4005 and 4006 movements.

The additional cutouts on the side are to access the dial foot screws and the alarm ring clamp screws on the 4005 and 4006 movements. On the 7A series movement, the holder holds the movement high enough to access the pusher levers.

THE MOVEMENTS IN THE IMAGES ARE FOR ILLUSTRATIVE PURPOSES ONLY AND ARE NOT INCLUDED WITH THE SALE. YOU ARE BUYING THE PLASTIC MOVEMENT HOLDER ONLY

The holder will hold the following movements, and many more that are the same size -
