The Piaget Altiplano 900P pink gold was launched in 2014 to mark the brand’s 140th anniversary, and this year, 2017, the 60th anniversary year of the Piaget Altiplano, a new pink gold edition has been introduced. It’s a limited edition of 200 pieces, available from April 2017, price €27,300.
It’s still the slimmest mechanical watch in the world at 3.65 mm total, and it’s interesting how Piaget achieved it. The caseback has become part of the movement, the mainplate. The dial was reduced in size and sunk into the thickness of the movement; parts of the bridges and wheels were left in view dial-side. The balance on the left provides a sense of movement, while most of the other wheels are moving so slowly as to be indiscernible. The video below provides a good overview of the design concepts.
The Piaget Altiplano 900P is 38 mm thick, with pink gold case and slate grey dial. The movement is hand-wound, runs at 3 Hertz, 21,600 vibrations per hour, and has 145 components including the case. The new 2017 edition is, I think, identical to the 2014 edition. Reference is G0A39110, and it costs €27,300. Read more on the Piaget website.
