Seamaster Pro 300m old Bond, stripped tube, help with part numer

Hi Guys, my first post here.

Recently my Omega's crown stopped screwing in (Semaster Pro 300m automatic 41mm 2531.80.00). I took out the movement and took pictures of the tube and inside stem hole. Looks like the thread is stripped. I was not able to check the thread of the crown because the thread is very deep at the bottom.

I'm wondering what tube to look for, screwed or press fitted. I should change the crown as well and that is rather clear. Can you tell me the part number of the tube? It seemed to me that after removing the movement, it would be easy to tell by the thread on the inside of the case or its absence. Meanwhile, the stem hole is quite small and it's hard to see anything inside.

Case Number printed on the caseback: 168 1623

According to an old Archer’s post, there were three tubes used on these Seamasters:
090ST4201 that is a press fitted tube
090ST1231 that is a press fitted tube
090ST4203 that is the threaded version

As far as I know, 090ST4201 does not have a collar in the middle, so this tube will not fit. What is left is 090ST1231 pressed version or 090ST4203 threaded.
Can you tell which version to look for by looking at the photos of the inside of the case and the outside of the tube?
Thank you in advance!

unfortunately the pressed in tube ;( Thanks!

To be absolutely sure….you need to lookup @Omega if it’s not a welded one. Then it’s not simply pressing in a new one.

You’re referring to the 2531.80.00 ? I make it a good habit to check as I had a welded version on my desk in the past where I thought it was screwed and I messed up there.
