Replacing Guard Pins
For the beautiful damaskeen finish found on the exposed winding wheels of high grade watches special equipment and some experience will be required.
Pitted end stones may be perfectly polished and restored as new by using a fine grade of diamond powder in oil on a tortise-shell lap running at fairly high speed in the lathe. Slight pressure for only a short time will restore them to their original polish.
Ordinary polish may be had on any flat surface after grinding with oil stone powder by finishing with a fine emery buff.
