Cover The Piaget Altiplano Ultimate Concept watch is only 2mm thick

Meanwhile, Bovet and Voutilainen were awarded the best ladies and men's watch respectively

A groundbreaking achievement in ultra-thin technology, the Piaget Altiplano Ultimate Concept won the prestigious “Aiguille d’Or”, which is the top prize at Grand Prix d’Horlogerie de Genève (GPHG) 2020. Measuring only 2mm in height, the world's thinnest mechanical watch arrived at its record-breaking feat by fusing the movement with the case, of which its material had to be specially engineered in order to be a viable working instrument. It also means that the movement components had to be subjected to unprecedented miniaturisation, an exercise that resulted in five pending patents. 

"It's an incredible recognition to our exceptional watchmakers, engineers and craftsmen, all the men and women that bring their passion, energy and perseverance to create the most unimaginable, the most unthinkable watch ever," Chabi Nouri, CEO of Piaget, said in her acceptance speech.

In the masculine category, Voutilainen 28SC received Men's Watch Prize. This wristwatch has the distinction of having an escapement with two wheels that directly deliver impulse to the balance, making it extremely efficient.
