Czapek reintroduces the fascinating handmade guilloché of the Quai des Bergues collection with a new design named “Résonance”. Intersecting circular lines form a pattern of bas-relief squares that make the dial come alive. This traditional technique was made possible by the rose engine lathe, which was devised in the late Eighteenth century and became a key machine in fine dial-making. The guilloché design goes back to François Czapek himself.
