Harry Winston’s latest addition to its Project Z collection is a lightweight, technical, and stunning timepiece.

Launched at Baselworld earlier this year, Project Z10 boasts an openwork dial composed of a blue anodized aluminum structure and a remarkably advanced mechanical aesthetic. 

Featuring a double retrograde display in an ultra-lightweight case composed entirely of Zalium – an alloy exclusive to Harry Winston – the watch is designed with an emphasis on ergonomics and comfort.  

This exclusive complication timepiece, while highly technical in nature, is quite versatile and designed for everyday life.

The 10th edition of the Project Z series and part of Harry Winston’s Ocean Collection, Project Z10 showcases a double retrograde movement with automatic winding through an openwork dial, whose skeleton structure reveals its meticulous finishes. Inspired by the Manhattan Bridge, this high-intensity technical design recalls the ambitious work of the early steel era, and the origins of the series, in terms of the case, strap, dial, display, and movement.

The case of the watch is carved from a block of Zalium and is mounted on a Shuriken-marked dual strap that is composed of black rubber and blue alligator leather. The combination of these materials adds to the exclusivity of this exquisite new creation of 42.2 mm.

At first glance, the Project Z10's dial reveals the intensely mechanical nature of this timepiece. The hours and minutes are off-centre, a signature of Harry Winston timepieces and particularly of the Project Z series. The hours and minutes counter consists of a black grid and a black satin-finish chapter ring with rhodium markers. The movement is visible and adorned with a spiral sunray centered on the hour and minute hands.

The frame of the dial features extremely fine openwork and is made of deep blue anodized aluminum, emphasizing the beauty of the metal. The watch is dominated by the striking relationship between the powerful gray of the Zalium and the deep blue of the dial structures.

The watch houses its movements in visible parts of the timepiece. From top to bottom, its mechanics, finishes, and shapes are at the forefront of the design. The open structure of the dial plays a genuinely meaningful role, as it houses all of the indications.

The hour is indicated off-centre. The HW3305 caliber displays the day of the week at 4 o'clock and seconds, on a scale of 0 to 30, at 8 o'clock. There is something special about these two indications; something that is at the heart of the Project Z's identity: they are both retrograde. The hands travel 120 degrees, instead of making a full revolution.  At the end of their journey, they automatically jump back and resume their operation.

Project Z10 intentionally reveals the functional elements that perform these mechanical operations. For example, the gear that directs the second hand, is perfectly visible. The technical nature of this timepiece is more than just a design choice; it is an iconic quality that the Project Z series is known for. The caliber is regulated by a silicon balance spring, which guarantees exceptional long-term precision and stable operation.

The edition is limited to 300 timepieces.
