What Is the Guilloché of a Watch?

Audemars Piguet

Guilloché (phonetically pronounced gee-oh-SHAY) is a form of decoration for watch dials, which give the dial depth and visual complexity as you can see from the Audemars Piguet example above.

Guilloché is most often applied to silver and black dials via a decorative engraving technique highlighted by precise, intricate, and reptitive design or patterns mechanically engraved into the dial surface.

It is named after the French engineer Jean-Pierre-François Guillot-Duhamel (1730-1816), who invented a machine that scratched intricate, fine patterns and designs on metallic surfaces.
