Our workshop can do a basic Grey scale for watch dial restoration or personalisation.
The basic colours are: Silver, Rhodium or Black Pearl.
You can see the basic colours in these Pictures. The first picture is in black background and the second is in white background. The idea is to compare in the best possible way the different range of grey in the dials by changing the background.

In the following image we can see a complete restoration in silver background:
