Piaget Altiplano Ultimate Automatic G0A43120 Sold Prices & Listings

After launching the world's thinnest watch with the 900P in 2013, Piaget unveiled the 910P in 2017, Achieving a thickness of 4.3mm, Beating Bulgari's previous record of 5.15mm for an automatic watch by almost a millimeter. Inheriting the technical solution of the 900P, Which was the world's thinnest hand-winding watch at the time, The Caliber 910P utilizes the caseback as a structural support for the movement components, Forming an inseparable, Integrated unit between the case and the movement. In other words, The case and the movement are one. The upper surface of the caseback acts as the main plate, Completely eliminating unnecessary layers. The off-center dial is positioned in the space between the bridges visible on the front, And the entire gear train surrounds the dial, With every element, From the ratchet wheel to the balance wheel, Visible. Despite this extreme construction, The watch boasts a 50-hour power reserve. The peripheral winding system, Which rotates around the edge of the dial (and movement), Eliminates the vertical space occupied by a conventional rotor. The narrow rotor, Mounted on the edge of the movement without adding thickness, Is crafted from 22K gold and mounted on ball bearings for sufficient winding efficiency. The details don't end there. The off-center dial sits slightly lower than the surrounding bridges, A step below. Even if excessive pressure on the crystal causes the case to slightly curve, The bridges protect the hands, Preventing contact with the crystal. The Altiplano Ultimate Automatic represents the ultimate in ultra-thin watchmaking, Blurring the lines between case and movement, Demonstrating Piaget's technical culmination in pushing the physical limits of watchmaking.
