The anthracite skeletonised model with a ­45-mm case is made of stainless steel and has a satin finished surface. The struts between the recesses as well as the six riders of the bezel are polished. A glance behind the case which is coated in black PVD offers an open view of the manufacture calibre ML234. This is structured bridge for bridge through five concentric circles and appears from the centre of the spring barrel at one o’clock. All components of the manu­factured movement are open and bead blasted, from the spring barrel to the flywheel.
