PIAGET unveils a new addition to its Polo series, featuring a perpetual calendar complication. The watch continues the unique “round exterior, square interior” case design, with one model boasting a natural green obsidian dial paired with an emerald bezel, seamlessly blending the colors of both gemstones. The other version features a deep blue obsidian dial, where the unique gemstone texture evokes a serene, mesmerizing starry sky.

The new watch is housed in a 42mm platinum case, just 8.65mm thick, finished with horizontal brushing and mirror polishing to create a delicate play of light and shadow. A hidden button at the 9 o’clock side of the case allows for quick adjustment of the perpetual calendar functions. The green obsidian version features a bezel set with 56 progressively sized emeralds in brilliant-cut, each perfectly matched to the contour of the bezel. The high level of precision required for selecting and setting these gemstones is evident in this stunning detail.

The square-pillow-shaped dial is made from obsidian slices, a natural gemstone formed by the rapid cooling of volcanic lava. Polished to a mirror-like finish, it has an iridescent sheen and unique texture that makes each piece distinct. The dial continues the classic layout of the Polo Perpetual Calendar watch, with month and leap year at 12 o’clock, a date display at 3 o’clock, a moonphase window at 6 o’clock, and a day indicator at 9 o’clock.

The watch is powered by the PIAGET 1255P automatic movement with a frequency of 21,600 vibrations per hour and a 42-hour power reserve. This ultra-thin movement is built with an off-center rotor layout, and its thickness is just 4mm, ensuring the watch’s slender profile.
The blue obsidian version comes with a blue rubber strap, priced at ¥810,000 RMB. The green obsidian version with the emerald bezel is limited to 18 pieces, and its official price has yet to be announced.
