Hi all, new here, I normally resdie over in the Rolex area, however my better half treated me to a V5 42mm PO for Christmas.....unfortunately there are a couple of problems with it 
the first is the crown won't screw down, I'm pretty sure that this is the due to knackered threads, the second is it doesn't work, so I've ordered a new crown and tube and a new movement. While I'm waiting for these to arrive I figured I may as well get on with removing the old tube So here goes!
BTW this is not meant to be a tutorial, just a record of what I did and where I went wrong, or, fingers crossed...right!
The offending crown!
First job was to get the movement out of the case, this means of course undoing the back and then undoing the movement screws, of which one seems to have totally disappeared! Oh well, one less to undo!
Once they were undone it was time to remove the old crown and stem...I was far too nervous during this to take pictures!! So worried I was gonna screw this part up! Luckily, all went well and the crown and stem came out ok Next up the movement and retaining ring were removed and finally I could get a proper look at the job in hand.
Now it looks to me like the rep tube may well be screwed in, judging by the thread I can see in the case, so I'll try and unscrew it first. I tapped the case up just in case I slipped, be a shame to damage my lovely PO before I've even worn it!!
Yep sure enough it unscrews, which is a nice surprise, I think. All the reading I'd done before I started this seemed to suggest the rep tube would be a push fit. This one I just grabbed with pliers and gently unscrewed
And hey presto, without drama or damage, it was out!
Here is the old, slightly squished tube!
So all that was left to do was clean up the case threads and now sit by the front door and wait for the postman!!
