The flat nose pliers is hard to open and not close properly. The spring is too weak. Having reworked with a file, it works now after all I do okay. For delicate parts it is already too coarse. But I already have a whole set of small pliers. So for me no problem.
Most other parts I've tried in watches or spectacles. That all works. The blue Stiftaustreiber seems to me to be redundant, because you can also watch straps with the gray block cut plus each calcinations. I missed a pair of tweezers made of plastic. The existing is made of metal and works well. But you can so easily cause a short-circuit the battery.
However, one should not underestimate the difficulties in the exchange of watch batteries. When the watchmaker always looks so easy, but it is not. My experience with 3 watches:
1. Clock with blasting cap
She goes on smoothly and that battery replacement is somewhat fiddly. Everything OK, but I would have not required the special tool.
2. Clock with snap lid
It shows no place for attachment of the knife. After a few failed attempts and some scratches on the clock I give up. The next day I watch the watchmaker's shoulder. He, too, has problems with the tight Uhrdeckel. But I know where the knife has to be recognized. Although the battery is now changed, I'll try again with the knife: It works. The knife has withstood the loads fine. I need an extra base insert clamp to close. The power is not enough for it, and with a hammer ...
3. clock with screw
I get the clock with the Kastenöffner not. But that is not to the tool, but due to the limited power of the fingers for holding the housing. Possibly it would work with an additional case holder for the clock. But again, the tool has suffered no damage.
