Watch Caseback/Crystal tool Press Die Adapters

Here are 2 adaptors so you can use your watch case-back and crystal press dies on different brands of tool. The first allows the use of threaded dies on the Robur press and the second allows the use of Robur dies on threaded type presses.

One uses a standard M6 bolt to allow it to use the threaded type dies, I recommend a 14mm length bolt.
