Spring movement holder, the design of these is good you push the ends together to open holder, put movement in, then the spring closes and holds the movement, so no screw winding very easy to use.
This has been one of our best sellers when was made of plastic so we have now upped the quality of the spring and made the tool of aluminium blocks so is an even better bit of kit.
Colour may vary.
