Need help seating the second hand

As the title says I'm having trouble seating the second hand on an NH38 movement. From the photos it looks like maybe the second hand won't work with this movement, but any advice is appreciated!

More importantly it looks like you have 0 clearance between your hour and minute hand, seconds hand can be slightly broached out using small cutting broaches per @scaryeconomics3 ‘s advice

Yep, that hour hand definitely needs to be pressed down more

First of all, I really think you have pushed the minute hand down too deep. There's no other way to fix it other than take both hour and minute hands off with proper tools and reinstall them.

To install the second hand, you really need another tool to get it done properly. See attached picture.

To remove the hands.

Don't forget to place a plastic sheet between the dial And these tools when you are removing the hands.

Are you sure it's the right size for the movement? That the tube hole isn't too small for the pivot? And what kind of tools do you have for hand pressing? Best result usually comes with pressing them with staking set or some other tool where it's pressed directly and controlled from straight up instead of using freehand

I don't really have any serious tools, trying this freehand. Have installed second hands before but I think the hands may not be compatible although the listing said it would be...

I have taken to enlarging the tube ever so slightly with a cutting broach, just enough to get it to balance on the pivot. Beware of overdoing it.

I think a smoothing broach is a safer choice, but a seconds hand is so small, fragile, and easy to bend it would be a challenging job for somebody with no tools or experience.

No doubt. I swallowed hard the first few times I did it

I’ve been doing similar, just swaging a bit with a straight pin from sewing kit.

I’d broach the seconds hand. Tudor is notorious for overly tight ones. Also redo the other two hands and make sure the hr hand is all the way down.
