Hi all, I'm about to service my 861 Speedmaster and I don't own a Jewel Press or Staking Set, When I come to reassemble the movement I need to hold the Chronograph runner Jewel while I press fit the gear to stop the Jewel from being pressed out from the other side... so, can I use this movement holder I bought from Cousin's for the 861 ?.. or am I wrong and need to buy a Staking Set ? thank you all in advance (I will clean off all the dust first of course)

Up date, I've bought a Staking set and parts, I should have just done this in the first place !
