Miles Davis

Oris “Miles Davis” - The Birth of the Cool. The Oris Worldtimer is a miracle of miniaturization. Few challenges in the long history of Oris have been as demanding as the development of this minor marvel. Its movement - Cal. 690 - is the result of cooperation between engineers, customers, watchmakers and highly specialized manufacturers of miniature mechanical parts. Micro-mechanical achievements of the highest order have gone into its making - the sort of precision for which Swiss expertise is a byword. Take the "Roue minuterie II assemblée" as an example of why 1/000 millimeter is of such importance to the Oris Worldtimer. At first glance all you see is a miniature cog wheel. But put it under a microscope and a whole new world of mechanical wonders is revealed - a cog wheel made up of four parts with three separate toothings. The smallest cog wheel has a diameter of 0.75 mm and 9 teeth.
