And to be fair, some of Cartier's less-accessible pieces, like the Rotonde de Cartier Masse Mystérieuse (Ref. #WHRO0082), with the movement inside the rotor, or the Tortue Monopoussoir Chronograpph (Ref. #CRWHTO0008), with its shaped, hand-wound chronograph movement, do offer more purely horological interest for the so-called "savants". ;-D
