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. Attached File  Screenshot_2015-10-16-12-09-08-1.png   106.82KB   13 downloads

I give the backs and sealing ring a wipe with a Punch self shine sponge.....I know what you mean though.. You get that sweaty panicky feeling.....You hear the snap and wonder if it's the back that's clicked in or the glass that's gone...

We've got both these presses & both round and square dies. But we also have one of these case cushions, which is really useful for the more odd shaped watches and for when the dies just aren't right.

Robur, and Silicon sealing grease NOT a f##king shoe shine sponge!

 

You can always think outside the box too. When ever I fit a press in curved glass I make a press using polymorph. I don't see why it can't be switched the other way to make a case back press if needed.

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.

Does the die set for the Robur cover more/less/same as the Bergeon?

looks to be a similar size range, i just think you will get more pressure from the robur tool, as you are screwing it down rather than hand squeezing

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?
