Hi Johnnie ,
Hopefully you didn't inadvertently knock the yoke off of the groove on the clutch wheel . If the little button is stuck down , that means that the setting lever is not seated properly and not allowing the small nub on the setting lever to engage the grove on the setm.
This happens sometimes when replacing the stem . First thing is to use the stem and crown or a small screwdriver in the stem hole to gently wiggle the parts into alignment . Doing this will work more often then not .
If this doesn't do the trick you have to remove the dial to access the setting / winding mechinism to align the parts ,...usually the yoke back into the clutch groove as I previously mentioned . Your watch is a bit more complacated because of the gear that turns the inner rotating bezel .
Attached is the PDF tech sheet for the Seiko 6106 , which is the base movement for the 6119 . You can see the parts I'm talking about ....Good Luck....
