According to B.R.M, the Birotor represents 30 months of testing and prototyping. The case is made of titanium (~40mm x 48mm) and has a slight curvature to it. The top and bottom sapphire glass is curved as well, and there are also glass inserts on the side of the case which offer additional views of the movement. (via B.R.M Birotor Watch | Perpetuelle)
