Featuring a zalium case – a material used exclusively in watchmaking by Harry Winston – Project Z6 announces the arrival of a new complication in the collection: a 24-hour alarm on a hand-wound movement specially developed for this timepiece and exclusive to Harry Winston.

Adjusted by the crown, the striking-mechanism for the alarm is activated by a trigger at 4 o’clock. The hammer, which is fixed to the case, can be admired through an opening on the dial, while the solid rectangular gong produces optimal resonance.

Thanks to its two barrels – one for the movement, the other for the striking-mechanism – Project Z6 has a 72-hour power reserve. And matching the complexity of the 18-level movement, the off-centre dial reveals two overlapping disks that display the time and the alarm’s striking-mechanism. This series is limited to 300.
