Manufacturing process
We carefully sculpt every dial detail in CAD software and then CNC machine a series of stamping tools with increasing fidelity. These are then used to stamp brass blanks in multiple stages, adding finer and finer details. Next, we apply multiple coatings, lacquers and fumés to establish depth and dimension. A final layer of clear coat is polished to a glass-like finish, resulting in a truly captivating visual experience. The applied logo and indices ensure contrast and legibility, while the ultra-sharp diamond-cut hands complement the intricately finished watch case. Additionally, all elements are coated with applied Super-LumiNova BGW9 for optimal visibility.
