Obviously, in any market, there is the price of choice. Choice is what it is all about. However, at first sight, and at first impact, the use of the esoteric materials and metals seems obvious. Find another metal or material not used before, manufacture the watch part(s), and test in the watch. However, not quite as easy. At times, it takes years for Richard to get an idea right. Sure, he has the idea, but then the material and/or technique takes time to work out. Most of the limited series tourbillon watches have taken 18 - 24 months to work out on the materials alone. The extreme example of this was the RM018 with the gear train from semi-precious stones.
