There is a distinctly sporting vibe to the Project Z9 flyback Chronograph in Zalium™, a highly durable, ultra-light and anallergic alloy that is exclusive to Harry Winston. This is also the first Project Z9 watch to incorporate a high-frequency movement: the new HW3304 calibre with silicon balance spring. Beating at 36,000 vibrations/hour, it delivers the enhanced precision required to measure elapsed times to 1/10th of a second. The dial is composed of an openworked grid that carries timekeeping indications. Raised chronograph counters accentuate the three-dimensional effect. Like its predecessors, this ninth watch in the Project Z series is produced as a limited series of 300.
