We took the case of the 2020 GPHG-finalist 27.01 and found some more internal space. This was sufficient to add a sapphire dial (necessarily thicker than the brass dial of the 27.01) and a blue Clous-de-Paris guilloché ring around the periphery of the movement, without any increase in overall thickness. In addition to our core elements of radial symmetry, legibility, the 0 marker and flared lugs, we extended the smooth visual transitions beyond the case lines to the dial itself. We added a gradient to the lower surface of the sapphire dial and laser etched markers on the upper surface, causing the guilloché to appear to fade in not just depth and spatial frequency but also saturation. It transitions from an inky black center to prominent guilloché at the edges and exhibits our trademark inversion under certain angles – with the markers appearing to float over a uniform mirror.
