Watch case backs that won't go back on without a fight


Recommended Posts

Do you get these often? About one in 20 watch backs we open pop off with a large amount of force and I just KNOW they are going to be a pig to get back on.

 

We have a combined case back /glass press tool but I really wasn't convinced this was going to do the job without smashing the glass on the last tricky case back I did, and yes, this despite using the right die which is pressing on the frame not the glass.

Any tips? Anecdotes? Thanks :)

This my press. Smaller, cheap, puts pressure in gradually rather than in one go. I have extra dies including extra large and square ones. Haven't broken a glass in over twelve years ( you've probably jinxed me now.)

Make sure domed glasses aren't touching the dies. Pressure on the frame not the glass ( which you do)

Top die covering as much of the back as possible. Screenshot_2015-10-16-12-09-08-1.png

We had no end of problems refitting watch backs with a cheap lever press and plastic dies that warp and even split. We invested in the Robur kit and haven't looked back. The screw action of the press gives great control and the alloy dies do not warp.

I have one of these.  Having a horrible struggle with a Tissot back which refuses to go back on even with the press :(  Any tips?

This is the one Lee, the gasket is set in around the movement case.  Should it come out and fit onto the back before pressing?

i'd put the gasket on the watch back to be pressed on, just be careful not to kink the gasket or you will probably need to order a new one, also, i can't remember if they go on a certain way, hope that helps

Thanks Derek,

 

Got it back n eventually by putting the gasket on the back then trying again.  Nightmare!
