In-Depth: Piaget Debuts Thinnest Tourbillon Watch Ever
Piaget does the unexpected to mark its 150th anniversary. Instead of a special edition of an existing timepiece, Piaget has profoundly reworked the Altiplano Ultimate Concept (AUC) – endowing it with a flying tourbillon. The thinnest tourbillon ever by some margin, the Piaget Altiplano Ultimate Concept Tourbillon 150th Anniversary measures 41.5 mm in diameter and stands just 2 mm high, crystal included. In other words, Piaget installed a tourbillon in the AUC while maintaining the same overall height. Initial thoughts The original AUC of 2018 was an impressive example of micro engineering. The innovative movement construction resulted in a case thickness of just 2 mm, while still managing to look like a conventional watch, as opposed to the panel-like appearance of the even thinner Richard Mille RM UP-01. Now Piaget has built upon the concept by adding a tourbillon to the slim construction. A tourbillon is not a practical addition, since chronometry was never the main point of the AUC. Instead, this is an exercise in pushing the limits of micro engineering. Piaget’s engineer surmounted the challenge and the result is nothing short of amazing. It’s crucial to note that adding a tourbillon to the AUC is not merely adding a tourbillon. Practically the entire calibre was reworked – according to Piaget one 90% of the parts are new – right down to reducing the number of spokes in the wheels to minimise energy consumption. Beyond its mechanics, the AUC Tourbillon also...
