The multi-layer dial showcases several technical innovations, the most striking of which is a 1mm sapphire disc featuring a distinctive, liquid-like surface. This effect is achieved through advanced 5-axis CNC machining, followed by meticulous semi-polishing to create the desired finish. Each CNC machine produces only 6–8 discs per day, with a yield rate of approximately 50–60%. During the surface-finishing stage, a single polishing unit can process around 20 pieces per seven-hour batch, also with a yield rate of about 50–60%.
Beneath the sapphire layer lies the base dial, which incorporates seven carefully applied layers of custom-formulated Super-LumiNova pigment. Each layer must be allowed to dry fully before the next is added, making the process exceptionally time-consuming but essential for achieving a vivid and uniform glow.
