Guilloché: A rediscovered craft
At the time of its creation, the technology of guilloche was used in particular as a security feature when printing banknotes, bonds, passports, and identity documents, since guilloches on the engraved printing plates used at the time were not easy to reproduce. In the more recent past, guilloches have been used predominantly as an engraving option for watches and jewelry. In contrast to printed guilloche patterns, this also takes the spatial design of the pattern in the material into consideration.
In the last years, a few manufacturers from the jewelry, watch, and writing device industries have rediscovered the art of guilloche. Otto Hutt is one of the few companies that continue to use this challenging technique. The business has not only continued the precision process manually, but also further developed it to include an innovative CNC-control.
