Knowing how frustrating it can be to find an unfinished thread requesting help with a specific problem, I'm trying to post the answer to the threads about VSF NTTD crown and tube issues.
With hat tip to
@daytonadude, no need for those half-assed "fixes" because a solution has been found!
A compatible crown and press-to-fit tube are available on
AliExpress. Assuming this problem will keep coming up after the links here have cone dead, persons in the future may try a search for "
High Quality Stainless Steel Watch Crowns Titanium color For Seamaster 300 6.3mm*2.5mm*2.5mm Watches Accessories Crown part" or look for
HJWEI Watch Movement Store.
If your tube is stripped, you will need to remove the tube. It Is press-fit and, based upon my experience, may not be easily pressed out without the soft metal mushrooming making it impossible to remove without cutting it out. In retrospect, I think using a screw extractor bit may prove more efficacious than trying to push the VSF tube out.
If your crown is stripped and the tube is fine, measure the tube diameter and select the correct size tube from the options. I bought the 6.3mm crown that comes with the 2.5mm * 2.5mm tube which did not fit my VSF crown. No problem, though as I just used the new crown (see pictures). I have no way of knowing since my tube was beyond measuring but the 2.6mm*2.4mm tube may fit the VSF crown. Again, it's just a guess but, again, if it doesn't match, just use the new crown that comes with the tube and your good to go.
So here are the pics of the new crown and tube installed. Please note, the second photo of the crown (side view) was after I hit the crown with the torch (after first removing the rubber gasket) to darken it as I felt it was just a bit too brite out of the box. So the two views show the lighter crown (front view0 and the darkened crown (side view) so you can decide for yourself which is better.
