Hi, can anyone identify this tool? I Don't know at all what it can be. It is 16 cm (like 6-7 inches)long and material is brass.

Hi

I have never used one, but it is a pivot lathe or also known as a Jacot tool, there are normally a few more parts that go with it.

From the "Watch Makers Repair Manual" by H. Fried it states; "The tool is known to English-speaking watchmakers as the "Jacot" tool. This tool undoubtedly offers one the very best methods of reducing or polishing pivots to size & shape."

Tom, thanks for your help! Now, with the name of the tool, it's easy to find information on the net. Even a movie:
