Meet the skinniest watch in the world

In 1957, Piaget introduced its 9P manual movement, which, at only 2 mm thickness, established the brand as the reigning authority in ultra-thin watchmaking, a specialty it has excelled at ever since At January's Salon International de la Haute Horlogerie in Geneva, Piaget unveiled its latest achievement: the Altiplano Ultimate Automatic 910P With a thickness of just 43 mm, it marked a new record for a skinny automatic.

Piaget also showed off a concept watch - the Altiplano Ultimate Concept - which is about as thick as a quarter, with the entire watch measuring a tiny 2 mm deep Bulgari, a newcomer to ultra-thins, has engaged in a bit of an arms race with Piaget in claiming such records Last spring, a few months after the 910P debuted, Bulgari revealed its 395-mm-thick Octo Finissimo Tourbillon Automatic, which beat the 910P by a fraction of a millimeter, even with the addition of a tourbillon.

Legendary watchmaker Abraham-Louis Breguet patented his tourbillon mechanism in 1801 The immaculate, white Grand Feu enamel dial - with an off-center chapter ring at 11 o'clock, balancing the tourbillon at 5 o'clock - evokes A.-L Breguet's groundbreaking work. Source
