The prototyping and work done in his workshop in the Vallee de Joux is done the "old-fashioned way." Tixier assured me that their new movement is not a result of using new CNC machines or manufacturing techniques that wouldn't have been available in the past. If he could prototype it largely by hand with 60 or 70-year-old machines, it shows that the watch was a testament to link an idea, not new materials or technology.
