Help replacing chronograph pusher tubes

[Chopin]

Can someone tell me if these tubes are replaceable or not ? While trying to remove one I managed to damage it badly. The thing that makes me think that they are not part of the case is the fact that they both sit at different heights inside the case. Are these screw in ?

Trying to unscrew the damaged one but it doesn't seem to move.

The reason I wanted to remove them is stupidity and the fact that it's missing a pusher so for some reason I thought that it was appropriate to try and remove the tubes. I've done a  booboo, I know.

Yes they are. They are likely threaded. Youll need a special splined screw tool. Horotec makes them.

Hi from what I have seen of these tools they are much like torx drivers may be some of these will do the job

Equivalent tool for a much more reasonable price.

I won't be attempting to remove the other, the problem is that the one that I tried removing is now really damaged and needs to be screwed out.

Any tips ?

Unless there is damage to the inner side or how the pusher works, leave it alone.

The damage is bad. It has to be replaced. I have to get it out.

You can use a screw extractor. Search Internet to see what is that. Heat well the case around the tube before and proceed carefully.

Lol. I was trying to be all watch maker uppity....the one you shared is actually the one I have. Ive learned that for every ridiculously overpriced watch tool there is a cheap chinese knock off. The trick is knowing when the knock off is decent enough. Some times the chinese knock offs arent worth the cost to ship them.

I believe Bergeon makes single size tools as well. They run about 50 bucks each. For the large pusher this spline set works too.

Alright, I managed to extract what was left of the tube.

Guess what ? It was a freaking push in tube, not screw in.

I thought that those that have those little threads/spikes on the edges are supposed to be screw in... Oh well, another lesson learned. Thanks guys! Panic mode off.

I had tried pushing it out but couldn't so assumed that it's screw in.

Out of curiosity, is it possible to extract these push in (or should I say drive in) tubes without one of those expensive tools ?

Once I was able to install the tubes by using a crystal press (and improvising a bit) but don't know I could go ahead and remove the remaining one. The reason I'd like to remove it is to measure it so that I'll know what replacements to order... Do I even need to know the dimensions of that tube ?

Nice. Thanks for the tip. I could have probably saved myself a few bucks and heartache had I known.

I have done something like this before. I ended up using pliers to clamp the opening of the tube shut, creating a nice flat end for me to grab and twist, with said pliers.

  they are listed in any tool catalog  - you can make the square ones out of "key stock".  vin

Here's a moderately priced tool for friction tubes https://www.aliexpress.com/item/10000014322393.htm

When improvising is always better to build a something that does not cause any damage and can be used again for a next time.

Managed to remove both of them and they got damaged in the process but one pusher was missing so I'll get a new pair anyway. The thing is that I've looked a bit on CousinsUK and so far those on the website don't exactly seem to fit my required dimensions.

For example all pusher diameters are in increments of .50mm. Mine is 4,8mm I believe... Being bigger might not hurt but the hole diameter seems to be 5,2mm so I'm not sure if it'll be a safe fit. Same goes for other dimensions as well, hopefully I'll manage to pull this through.
