Piaget Altiplano 900D Review – Ultra-Thin High-Jewelry Watch
The Piaget Altiplano 900D is a landmark high-jewelry creation unveiled at SIHH 2016. Combining ultra-thin watchmaking expertise with a fully diamond-set dial, this model represents Piaget’s pinnacle of elegance and technical mastery.
Ultra-Thin Architecture & Movement
Following the design philosophy of the Altiplano 900P, the 900D integrates the case and manual-winding movement into a single structure with 145 components. Measuring just 5.6 mm thick, it holds the world record for the thinnest high-jewelry wristwatch. Through the sapphire crystal, the balance wheel at 7 o’clock and gear train are visible, combining visual appeal with mechanical efficiency.
Exquisite Diamond Dial
The dial is adorned with 304 diamonds totaling 5.77 ct, requiring four days of meticulous gem-setting. Step-cut diamonds frame the outer dial ring, while snow-set diamonds cover the main plate, enhancing legibility. Even the bridge screws and gear components are diamond-set, creating a harmonious sparkling effect across the entire dial.
Case, Strap & Wearing Experience
Housed in a 38 mm white gold case, the watch features the 900D manual-winding movement with a 48-hour power reserve. A diamond-set outer ring on the caseback emphasizes the jewelry aspect, while the alligator leather strap ensures elegant comfort. Water resistance is rated at 30 meters.
