Guilloche: Patterns on a watch dial

Engraving on a watch dial can add real beauty to the overall appearance of the watch.  Guilloche is engraving technique done using a machine controlled by a skilled artisan .  Now you make think the machine is dong the work but you would be wrong.  The user is controlling it and the machine is helping to carve the material out of the dial.

Seeing it does give you a massive appreciation of how long it takes and the skill involved to achieve such a result.

I have found a couple of videos that provide the visual aid needed to fully appreciate this skill.

The first is from Vacheron Constantin

The 2nd video is from RGM, which is Roland Murphys company based in Lancaster Pennsylvania in the USA.  He gives a great explanation on how the machine works.
