Featuring an escapement mounted on gimbals, as in a marine chronometer or gyroscope, the Zenith Christophe Colomb Tourbillon is a unique beast. It keeps the escapement level at all times. An interesting and innovative concept that takes the idea behind the tourbillon further. This is a limited edition of 25 pieces. – SJX
To be presented at Baselworld 2011, the Maurice Lacroix Masterpiece Roue Carrée Seconde features a pair of rotating, enmeshed square wheels on the dial. Conceived by watchmaker Michel Vermot, who is now head of Movement Development at ML, the wheels are made by LiGA technology, a photolithography technique also used to make silicon parts for movements.
This is the first time square wheels have been used on a production watch. According to ML, “The square wheel, whose corners and contours mesh with the same precision as its circular counterparts, is activated by a toothed clover-leaf wheel and turns continuously to create an extremely dynamic visual effect.” Click here to see an animation illustrating the motion of the square gear on the dial. The watch shown in the animation is the Masterpiece Regulateur Roue Carrée launched in 2010, not exactly the same but identical in turns of gear motion.
