New special editions of Perrelet's emblazoned Turbine, each in a limited series of 250 and inspired by the world of casinos. These include the Turbine Roulette XL, in which the red and black segments of the famous "wheel of fortune" create an unusual pattern when the titanium turbine starts to turn. The white hour and minute hands evoke the colour of the ball thrown by the croupier. The design of the small ball appears discreetly below the turbine at the number 7. All the pieces in the collection have a steel case with black PVD treatment and are powered by the P-331 automatic calibre.
