Making of the hand-guilloché dial of the Chief Tourbillon

The grain d’orge motif on the Chief Tourbillon Guilloché dial is engraved by hand on a vintage Rose Engine Lathe dating back to the late 19th century. Through a painstaking process, each intricate line is carved over hours, with the movement of the machine and the watchmaker’s hand working in harmony to build the pattern. The result is a repeating geometry that brings depth, rhythm and texture to the dial. Peek into the art of making the hand-guilloché dial, where generations of decorative watchmaking tradition find expression in the second edition of the Chief Tourbillon.
