This is my personal design watch hands press. 

it comes with multiple pressing pistons with various sizes and movement holders for seiko, miyota and eta to perfectly align the movement with the press. 

Comes with a blank piston that accepts hand tools rubber terminals (the transparent head on the watch tool).

The press accepts also aluminium machined movement holders with a diameter of 36mm, like the ones sold on amazon. 

To make this work you need a 10mm x 40/50 mm spring, you can make one using my spring making Jig if needed.

Tolerances are quite tight, it might need some light sandpaper touches or passing the borders with an xacto knife.

Enjoy watchmaking !
