This Swiss watchmaker's micrometer, which was purchased on eBay by a CNC-mechanic for $25, is a rusty, beaten-up old thing that has seen better days. Until the mechanic restores it to a beautiful shiny tool that could pass for a work of art.
From his YouTube site:
When I was scrolling through the antique section of eBay and first saw this micrometer I wanted to restore it right away. I really like the unique look of those watchmaker micrometers. As a professional CNC-mechanic I'm very familiar with those measurement devices and I'm using them on a daily basis. The measurement range of this micrometer is from 0-25mm and you can measure exactly on 0.005mm. It was once re-painted to yellow, the original colour was black. That's why I decided to paint it black again. In the front of the micrometer there was a plate with the name and the location of the previous owner mounted with two rivets. The plate was in very bad condition and as I'm the new owner of it, I decided to make a new plate with my name and my location…I'm still very happy how this restoration turned out.
