When changing watchbands I used to struggle with a tool fashioned from a paper clip.  This was awkward and frustrating at best, damaging at worst.  The Bergeon 6767-F springbar tool has changed all that.  I now have actual control of the springbar plunger and am able to do a better job in much less time.  I used the tool just yesterday to replace a leather and nylon webbing "Swiss Army" style band and was very pleased with both the process and the result.  Specifically, where the band folds back on itself to make a tunnel for the springbar, there is a space on either side to insert the tool and engage the plunger.  It works!  In sum, this tool is recommended.
