專家說明
The present watchmaking tools are preserved in good, fully functional overall condition.
The hairspring vibrating tool is made to determine the correct length of a newly made hairspring. The hairspring to be produced is clamped on the movable pliers and brought into constant vibration with the original hairspring of the tool. By moving the clamping pliers, the vibration of the new spring can be adapted to the built-in hairspring.
The grinding machine is used for sharpening tools, comprising a grindstone and a support for the tool.
