Part of Citizen's new OF collection is the Sport Crono model, available in four different variants. The difference lies in the materials used for the case and bracelet, which range from steel tout court to IP Black treated, and in the colouring of the dial, in black, green or blue, with contrasting luminescent markers and hands. In common for all the fittings is the black bezel with tachymetric scale, the adoption of a mineral glass to protect the dial, the screw-down case back, a water resistance of 10 atmospheres and the movement with Eco-drive technology, which captures light from any solar or artificial source and accumulates it to be used as an operating principle instead of the common battery (the guaranteed autonomy is 270 days). Prices range from 219 euros for the steel version to 229 euros for the IP Black version.
