Lovecraft Posted February 18, 2012 Report Share Posted February 18, 2012 I noticed that my 42mm PO's tube is threaded on the outside, while pretty much all the pictures I've found of the tube switch process looks to be threaded on the inside (like the gen tube I got from cousins). My tube looks thicker and threaded on the outside - does it make a difference? Will it be harder to remove or will it leave a larger hole in the case? Is it a 42mm thing? I haven't seen anything about it really... t This is my case and my stem, in the picture above. That's Rymeister's stem before he removed it on his 45mm PO.

the_rymeister Posted February 18, 2012 Report Share Posted February 18, 2012 Just had another thought buddy I wonder if it is the internals of the rep crown that may have unscrewed from inside the crown? Quote Link to comment Share on other sites More sharing options...
Lovecraft Posted February 18, 2012 Author Report Share Posted February 18, 2012 Could be, but my AT's screw on crown looks the same. And I think my other watches at home are the same, not sure though. Quote Link to comment Share on other sites More sharing options...
It'sAboutTime Posted February 19, 2012 Report Share Posted February 19, 2012 The tube on my 42mm PO is also threaded on the outside. Quote Link to comment Share on other sites More sharing options...
the_rymeister Posted February 19, 2012 Report Share Posted February 19, 2012 It must be 42mm thing, I'm sure it will be fine fitting the gen tube, yours probably looks even bigger due to the extra threads on the outside. Quote Link to comment Share on other sites More sharing options...
sgtguk Posted February 19, 2012 Report Share Posted February 19, 2012 Just checked mine it's threaded on the outside too, might be a different batch I suppose Quote Link to comment Share on other sites More sharing options...
Lovecraft Posted February 19, 2012 Author Report Share Posted February 19, 2012 I opened it up and took a look inside. Seems to be an ETA, but not sure. It had the ETA stamps and so on though. No idea if they go to such lengths as to copy 0.5mm small logos... Anyway, seems it's threaded on the inside as well. Maybe I can unscrew it...

sgtguk Posted February 20, 2012 Report Share Posted February 20, 2012 My 42 has the threads on the outside, my 45 UPO has NO threads on the outside I assume that's the difference in the two Quote Link to comment Share on other sites More sharing options...
Lovecraft Posted February 21, 2012 Author Report Share Posted February 21, 2012 Tried with pliers yesterday, but all I managed was a small nag in the case, despite being careful. I hope I can remove it. Either way, I'm pretty sure I won't be able to use pliers to remove the tube. I'm going to file a little in an X-sign to make traction for a screwdriver, clamp it, and then simply try to unscrew it. If that doesn't work I will clamp it properly to a work table and drill it away. I have to wait until I get my small screwdrivers though (taking their merry time on route from Hong Kong...) - don't want to do any screwing or drilling with the movement still in place.

the_rymeister Posted February 22, 2012 Report Share Posted February 22, 2012 I had the same dilemma when I was trying to remove my tube from the cas, when I got to the point where the tube was crushed and there is no way out I used a small screw driver as I didn't have a chisel or punch small enough and knocked it out from the inside of the case, came straight out with about 2 swift taps with the hammer I got in the watch tool kit You've probably less likely to damage the case by knocking it out rather than using pliers Quote Link to comment Share on other sites More sharing options...
Lovecraft Posted February 22, 2012 Author Report Share Posted February 22, 2012 Indeed. I wish I could, but since it's threaded on the inside as well I won't be able to knock it out. I just hope they used a fairly weak threadlocker - if so, unscrewing it probably won't be that hard. Really hope I won't have to drill it away; it's the last resort.

Lovecraft Posted February 22, 2012 Author Report Share Posted February 22, 2012 Oh, and ironically enough (considering all the stuff I've ordered from Hong Kong and Shenzhen), my package from Cousins got stuck in customs. I just got a letter saying that they want to open it and inspect it. Quote Link to comment Share on other sites More sharing options...
Lovecraft Posted February 23, 2012 Author Report Share Posted February 23, 2012 Used a file to make a notch in the outer part of the case tube. I then unscrewed it with a screwdriver - it loosened easily. The inner part of the tube is slightly larger than the gen, and the threads are different so I will still have to epoxy it. The extra threads should give it decent retention. (sorry for the poor picture quality) Quote Link to comment Share on other sites More sharing options...

Lovecraft Posted February 23, 2012 Author Report Share Posted February 23, 2012 Progressing ever so slowly - most of the tools I need are still missing. Three weeks for some of the things. Annoying, but at least I get the time to do some research. Quote Link to comment Share on other sites More sharing options...
cougar1 Posted February 23, 2012 Report Share Posted February 23, 2012 Very strange, different tube than I've seen before, maybe it's just the way it looks in the photos? Quote Link to comment Share on other sites More sharing options...
shenns Posted April 3, 2012 Report Share Posted April 3, 2012 any news on the install? Im about to do the install this weekend and have all the parts ready.. Quote Link to comment Share on other sites More sharing options...
Lovecraft Posted April 3, 2012 Author Report Share Posted April 3, 2012 any news on the install? Im about to do the install this weekend and have all the parts ready.. Yes, it went really well. I used JB Marine Weld and a small vice. It really was quite simple. Just think through the procedure before hand and take it slow. Make sure to leave it be until the epoxy is firmly hardened. 1 Quote Link to comment Share on other sites More sharing options...
cougar1 Posted April 3, 2012 Report Share Posted April 3, 2012 shenns, there's loads of threads about the mod on the forum and guides aswell, covering all the trials and tribulations of those who done it and any potential problems along the way. The search function is your friend just lookup 'tube swap', 'tube crown' etc, don't even have to put in PO, most of the tube/crown swaps have been for the PO and it's the same process for 5th gen as it was for 4th gen etc. If you run into any hiccups let us know, good luck with the mod! Patience is the key, deep breaths etc, if you find yourself gritting your teeth, leave it for a half hour and approach it again Right I'll go now Quote Link to comment Share on other sites More sharing options...

First time opening a case back so i have my fingers crossed. Lovecraft, did you have any issues with the stem length or did the old one fit? I have the Asian 2824 will be using that most likely.

Lovecraft Posted April 3, 2012 Author Report Share Posted April 3, 2012 My old one was slightly off, but I think it was the wrong length from the start. I got some new ones and cut one to be the correct length. If your current stem seems to be the right length you probably don't have to modify it. Don't take my word for it though, it might differ a bit - just take your time and try it out. Quote Link to comment Share on other sites More sharing options...
