Louis Erard transforms traditional craftsmanship with this second hand guilloché dial masterpi ece. The Guilloché Main II elevates this technique beyond mere decoration to become the centerpiece: a striking diamond pattern with mesmerizing kinetic qualities. Rather than simply honoring tradition, this timepiece boldly pushes the boundaries of contemporary d esign. Each of the 99 limited dials demands hours of meticulous work by a master guillocheuse on a manual rose engine lathe. Behind the scenes, innovative engineers developed custom cams specifically for this groundbreaking creation, making it a true revolution in horological artistry.
