Hello everyone, isn't it a great skill in its own right to be able to make precision watchmaking tools. This little beauty is a balance poising tool with a sliding base and spring loaded vice to hold balance wheel in different position while you remove material from the balance wheel underside or rim side. The hand held cutter is sharpened by hand. I have used it on pocket watch and vintage wrist watch to make new balance out of scrap parts. But only once combined with hairsping vibrating tool for 18000 bph watches. A lot of fiddly work, but can be done
