Turning the machine over reveals a veritable panorama of meticulously finished micro-engineering through the sapphire sections.In a playful trompe d'oeil, what at first glance appears to be a micro-rotor in the form of MB&F's iconic battle-axe is actually a bridge.Indications: For a timepiece not developed specifically to tell the time, HM4 performs that role superbly.In fact, with its highly legible dials replica Corum 02120.102210 watch perpendicular to the wearer's wrist, Horological Machine No4 might be described as the perfect pilot's or driver's watch.On the left pod, the amount of fuel in the tanks - or power reserve - is clearly indicated by a skeletonised hand echoing MB&F's battle-axe motif.On the right, hours and minutes are displayed by bold, arrow-tipped Super-LumiNova filled hands.
Each of the two ation instrument-styled dials is directly controlled by its own crown, one to wind and re-fuel the tanks, the other to set the time, which provides direct and instantaneous feedback of the action performed.Case: Inspired by ation, more specifically the model aircraft kits of Maximilian Büsser's childhood, the case of HM4 imparts replica Corum Heart 80040.521410 watch speed, power, technology and refinement in equal measure.Visually, the case is composed of three parts: two streamlined jet-turbine-styled pods supported by a horizontal section housing the engine, which is clearly visible through transparent sapphire display panels and the central section of the case itself.
Case (continued): Technically there are also three main sections, but these comprise a fore section in titanium, which includes the dials and articulated front lugs; a central section in sapphire offering unprecedented 360° access to the superbly replica Corum 10140.406010 watch finished engine; and an aft section tapering down to the dual crowns and framing the animated balance, which is supported by an aerodynamic cock.Methods borrowed from aeronautic engineering are visible in the externally mounted screws, which provide both rigidity and watch resistance to hold the case's three sections solidly and elegantly together.
