The Project Z13 – named after their signature alloy, Zalium – has managed to maintain its position as a favourite for Harry Winston collectors.

The Time to Move initiative by the Swatch Group saw the brand break the boundaries even further as they introduced a moon phase display and a retrograde date in the range for the first time. In addition to this, the 42.2mm timepiece also saw the incorporation of Carbon with Zalium for the first time.

The open-worked dial features the moon phase display at the 6 o'clock with a Shuriken symbol to represent the moon. This symbol comes from the Project Z design vocabulary and is also followed throughout the design of the watch with its dodecagonal shape which hugs the cutout of the moon with its 12 facets. The fixed section reveals the moon crescents.

Equipped with the HW3202 calibre, the Project Z13 has a retrograde date which occupies the lower half of the dial. The autmatic calibre can be seen through the open-worked dial amidst the iconic Project Z blue which is present on the hands, the background of the starry moon disc, the date area , the Harry Winston emerald at 12. The watch comes limited to 300 pieces and sits on a black rubber-and-calfskin strap with matching blue stitching on top.
