Piaget Polo Flying Tourbillon Moonphase

Piaget’s latest release, the Polo Flying Tourbillon Moonphase, introduces a new level of complexity to the Polo collection—a combination of a flying tourbillon and an astronomical moon phase housed within a lightweight titanium case, powered by the ultra-thin calibre 642P.

The Polo collection was introduced in 1979 with a solid gold quartz watch, distinguished by horizontal gadroons across the dial and an integrated bracelet. In 2016, Piaget revamped the collection with steel cases and mechanical movements, expanding the lineup to include chronographs, ultra-thin perpetual calendars, and skeletonised models. The Polo Flying Tourbillon Moonphase marks a significant evolution, bringing together an anti-gravity regulator and a precision moon phase indicator in one design.

Titanium is a rare material in the Polo family. Before this model, the only Polo with a hint of titanium was the Ceramic Skeleton released in 2024. The new 44mm case is crafted entirely from titanium, with alternating polished and satin-brushed finishes that enhance its modern, sporty aesthetic. Despite its complications, the case remains slim at 9.8mm, thanks to the ultra-thin 642P manual-winding movement. The watch maintains a 100m water resistance, a reassuring feature given the openworked dial and intricate mechanics.

The case design pays tribute to the original 1979 model with blue PVD gadroons on the flanks, matching the ridged blue dial and the interchangeable blue ribbed rubber strap. The hollowed-out areas on the case sides resemble streamlined speed lines from the 1930s, adding a dynamic, sporty touch.

Blue is a signature colour for Piaget, and the dial of the Polo Flying Tourbillon Moonphase highlights this heritage. The gadrooned blue background frames the watch’s two key complications, arranged in a figure-eight formation. The upper section houses the flying tourbillon, suspended in a transparent well visible from both sides of the case. The tourbillon cage features a stylized “P,” reflecting Piaget’s attention to detail.

Below the tourbillon, the moon phase display is positioned at 6 o’clock. It features four silver-toned representations of the Moon—new, first quarter, full, and last quarter—set against a ribbed blue backdrop. A silvery hand indicates the current phase. This astronomical moon phase is exceptionally precise, requiring adjustment only once every 122 years. For manual corrections, especially if the watch is not regularly wound, there is a corrector on the case at 9 o’clock.

The dial also features a cushion-shaped, openworked area beneath the figure-eight formation, offering a view of the motion works, decorated with perlage. The applied indices and hands are filled with luminescent material, enhancing readability in low-light conditions. At the heart of the watch is Piaget’s calibre 642P, a manual-winding, ultra-thin movement that measures just 4mm in thickness. Originally introduced in the 2012 Gouverneur Tourbillon, this rectangular movement features a 3Hz flying tourbillon escapement and a moon phase display. The flying tourbillon’s cage is crafted from titanium, reducing weight and improving efficiency. At the same time, the screw-down caseback conceals most of the movement.

Despite its mechanical complexity, the Polo Flying Tourbillon Moonphase retains practical features. It is water-resistant to 100 meters and comes with an additional blue alligator strap that can be swapped easily thanks to a quick-release system.
