Spring bar tool conundrum…

I needed a fine-tip spring bar tool for my Omega watches, so I figured the fine Bergeon 6111 would probably be a decent choice.

But, I noticed that, not infrequently, I could not get a good purchase with the tip of the tool on the Omega spring bar, and often saw scarring on the bar after a number of failed tries due to slippage. Admittedly, I probably don’t have the perfect technique , but that might not be the end of the story,

I know the spring bar tip is not where it’s supposed to be to release the bar from a watch, but you will get my point (no pun intended):



The tip on the tool is a “V” shape; the spring bar is round, thus the interface between the two surfaces is not optimal.

Which leads me to my questions: in light of this, do any of you file the tips of the too, for a better fit? Is there another tool on the market, that’s fine, but has more of a “U” shape than a “V”? Thanks for any insights.

If Bergeon doesn't make a U shaped tip for the 6111, you might consider buying a standard tip and cutting it into a U, it shouldn't take more than a minute or two with a round file.

I just pulled out the Bergeon tweezers for a tip comparison: notice the “u” shape. Why not this on a regular tool?

These tips are made for use with various diameter spring bar tips, and there's no need for a round shape to make sufficient contact for removal. The intent is to position the tip above the flange and to push down on the flange, they're not intended to get a friction grip on the shank. And also, I don't think that people are generally concerned about scratching springbars.

Maybe the Bergeon 6767F would work better, I use it on almost all of my watches. Yours is the heavy duty version, maybe you’d get better purchase with the smaller 6767F below:

Thanks. So, which of the above come standard on the 6767?

Oh, I should have looked closer at the picture, mine came with the one on the right, 1.3mm outside diameter.
