Tudor Crown Problem?

Hi all,

So I just picked up a new black bay heritage Tudor in house. I noticed that when I unscrew the crown, it doesn’t automatically pop out to the winding position. I have to slightly screw it clockwise, and right when I do that it pops out to the winding position.

I read online that this happens with some tudors and rolexes, but some seem to think this is an issue. Is this normal? Thanks!

I just checked mine and it’s the same, I wish it was like my DJII as it pops right out and you can tell your winding.

The crown is an upside-down socket, and the top part of the (extended) stem has the flats (nut) that it must engage.

When it is unwound, if it does not exactly align socket-to-nut, then it needs to be moved one way or the other until it does. There is no issue, it is mechanics.

My Datejust II does the same thing - sort of sticks. No biggie

@Tools thanks for taking time to explain this, lots of ppl like me have never had a watch apart, maybe I need to see if there are some vids online that show watch disassembly just as a reference

I simplified the function for ease in understanding.

Here is a schematic... the right 4 pieces make up the crown mechanism and are a single unit, which is screwed on top of the stem, extending it for full function. When you press on the crown unit, it pushes the clutch-ring (socket) off of the piston (nut) and down around the shaft of the stem.... then you can screw it down onto the tube threads.
