So far in my watchmaker journey this is about the least desirable operation and I have the cuts to prove it.  I will only add that on several ebay beater training watches the only thing that worked is the "snappy" opener tool on Esslinger for about $12.

Good luck and may the force be with you 🙂

I never had a good experience with this tool. It's a modified automatic centre punch. The sharp point has been ground flat to a chisel point.

This tool tends to leave marks on the lip of the watch case. After that, it's impossible to get a water tight seal.

Apologies for my rubbish drawing and handwriting but I  had this idea a while ago.  Shape some metal to fit just inside the case back diameter, glue to the back, glue and nut to that and use mechanical advantage.

Damn, that is a good idea!!  Last night I was pondering gluing a nut and use angular force to pop it off, but this is far better!!  The shell piece easily 3D printed.

This is going for a sheer force pull over the whole back as opposed to popping one section of it, so requires...more effort, just that direct point loading on the lugs that bothers me, the outer case rim of the tool might want to be tight up to the lug joins and evenly distributed. Great idea though👍

Can't say I've ever been stuck for removing a back, screwed on or pressed on. 

The only time i have is when it wasn't actually removable, the watch put up a valiant fight,yet died a true hero's death 😄

Push against the legs isn't ideal but I think if the force is across all four ut should be ok.

Let me know how you get on.

I was trying to come up with a way to secure the case down so as to push against something else. I think you'd have to make something individually for each watchcase that fits close around the case backside as well as the lugs...a sleeve that just doesn't interfere with the caseback. Something like a ratchet socket but without the internal facets .

You could grind out the flats with a drum sander attachment.

If it works maybe Mark2 could use a jubilee clip to push against the lugs/case, fully adjustable. 

That reminds me of the adjustable mainspring winders that use 3 prongs to form an adjustable ring. You'd need to find a way of securing the top plate to the jubilee clip.

I was thinking a hole saw with the teeth removed

Better still 👍

This is why our group is so great...someone has a good idea and then we jump on board to build on it 🙂

Bugger off, Bergeon are going to pay me £1000, 000 for my idea, hehe. Joking apart, yes brilliant, if between us we can make a tool for stubborn back, then we all win.

I'm going to start calling you Thomas, as in Mr Eddison. Invented nothing, patented everything. 

Funny I was reading a few months ago about the ideas he stole from Tesla 😄

Just needs testing now. Do you need a nut above that plate ? 

Richard....I hope you are ready with a micro torch to re-weld all the lugs back on that this thing snaps off 🤣
