Harry Winston have released this uniquely designed Glissiere Tourbillon. The Glissiere Tourbillon’s movement is made of platinum and is completely visible through the sapphire crystal watch face, the design of the movement is clearly influenced by the locomotive of a steam train. The watch also features lateral windows in the case so you it is possible to see the movement working from the side. The watch also has a rather unconventional manual winding and time-setting system which must be accessed through the back of the watch to the barrel arbor and under-dial work respectively.
