Harry Winston have designed the Harry Winston Project Z6 Blue. This timepiece, which is part of the Project Z series, draws its name from Zalium, the lightweight yet sturdy zirconium alloy material the watch is made from. Powered by Harry Winston’s mechanical, hand-wound caliber HW1010 mechanism, this watch has the unique feature of a complex alarm with a minute repeater hammer that strikes a gong, emitting a crisp sound. This watch is also available with a DLC, or diamond-like carbon, finish.
