For this purpose it the workpiece holder well.
Positives:
* The design of the workpiece holder is stable. The thread and the guides have little game.
* The plastic pins for chucking the clock can be plugged into three different positions. So you should find the Auslangen in most cases.
* The workpiece holder can (and should) be clamped in a vise.
Negatives:
* The edges of the aluminum blocks are very sharp. In order not to make scratches in my watch, I have smoothed the edges with sandpaper and put a thin piece of fabric under when I chucking a clock.
* In order to even larger watch case clamp, I have the metal Bock turned the screw by 180 degrees, because the thread is not completely cut throughout the block. So I was able to gain the missing millimeters.
* The plastic pins have a smooth surface and are 90 ° to the aluminum block. Here some feel is needed to really clamp the clock well. Slightly longer and rougher plastic pins and a rejuvenation of the plastic pins downwards would be desirable.
Conclusion: conditionally recommendable and 4 stars. All in all, one can not really complain about the price.
