it looks to be a pretty nice tool in its box and everything, cheap, but for me it's zero, unless very good to use (there no instruction manual, but it is easy to understand: the wrist to enlarge shrink, the small central wheel to remove or expand away from pine nuts)) I tried two small watches, women, screw housing, bracelet with links, a little inconvenient for handling, and of course I had a terrible time to ask them properly my brand new tool, oh no, impossible. I felt much better manage with a simple penknife sharp knife, I opened with that many watches for gender répar'café Association (Paris) It helped me, there are large DIY fans out there, we did not come .This tool is only designed for screw watches (for others, Opinel knife awesome) Maybe for big man watches, then we can ask this tool more easily I say may - be. I am very disappointed with this gadget, it is useless to me. I opened 108 watches to date with my penknife. Needless to charges that cadget. Maybe I find the right tool, without difficulty, without risk of damaging a nice watch, thank you, if you have any advice for me. the service I render to my friends répar'café important to me, I am sad to see people leave with their shows without new battery. My complaint concerns only shows boxes screw, the other, I open without problems with my penknife, finely filed down. Try.
