Going Train Backlash on assembly
« on: April 02, 2014, 10:04:16 PM »
During assembly before putting the Pallet Fork back to the movement it is good habit to try the Going Train backlash.
This can be checked by turning crown until mainspring takes one click.
You should see escape wheel to spin and finally reverse significantly.

In the video the first twitch for me placing my finger on the crown. The start of  the backlash is quite difficult to spot.
