Roger certainly aims for an even more obvious connection to past practitioners of this style of finishing (Breguet and Daniels being the obvious references). I think CF has perhaps administered a slightly more modern take with the zirconium oxide dial, pvd application of numerals and text and less traditional case shape. But ultimately, they share quite similar methodologies and techniques: think CNC, proprietary escapement, strong links to George Daniels, meticulous and elegant finishing focusing on function more than anything else. Again, just my take on it!
