Guilloché Rosette
No. 18 · Watch dial engraving · Switzerland and France
Guilloché is the engraving on watch dials and banknotes: a cutter traces the same looping path again and again, shifting a hair each pass. Here that becomes 64 hypotrochoid lines with a drifting phase, building one 11‑lobed rosette.
Each hairline stays separate, even at full size.
