The engraving of highly refined repetitive geometric designs became possible with the introduction of the guilloche engine turning machine at the end of the 18th century. Cases and dials were generally ornamented with straight lines and spirals, although more complex patterns were also possible. The matt and shiny parts of the rosette on this case are built up of contrasting geometric patterns.
