If thin is in, Piaget has gone absolutely anorexic (in a good way) for SIHH 2011. Setting new haute horlogerie records, Piaget's latest luxury watch for men, the Emperador Coussin Tourbillon Automatic sets new records as the world's thinnest tourbillon.

Weighing in at 10.44 mm, thin self-winding tourbillons like Piaget's Emperador Coussin are extremely complicated because the oscillating weight that charges the watch mainspring when you swing your arms adds extra thickness to the movement. Piaget's Tourbillon Ultra-Thin breaks new grounds but being almost as thin as hand wound thin watches and here's a SIHH preview.

How an ultra-thin automatic tourbillon is possible

By combining two of Piaget's heritage calibres, the Piaget Calibre 600p, the world's thinnest hand-wound tourbillon and the Calibre 1208P, the world's thinnest automatic movement, you get the world's thinnest self-winding tourbillon- the Piaget Calibre 1270P. This technical and aesthetic masterpiece stands only 5.55mm thick and is a testament to the horological ingenuity (and three year effort) of Manufacture de Haute Horlogerie Piaget.

Piaget Tradition: Ultra-thin movements, Ultra-fine watches

Piaget has always played a pioneering role in fine mens luxury watches. Regardless of what you see in spy movies, always wear ultra-thin watches with your tuxedos, to do otherwise would be akin to wearing patent leather shoes to run a marathon. Thin mechanical movements began in 1957 when Piaget developed the Calibre 9P hand wound movement and followed up with the Calibre 12P self winding ultra thin movement only two tears later.

Piaget's latest in-house manufacture movement, the Calibre 1270P is 17th in line out of 29 movements designed and developed by Piaget. The Emperador Coussin Tourbillon's 1270P movement follows its forebears like the legendary Calibre 12P. Just last year, Piaget celebrated the 50th annivesary of the 12P by releasing the thinnest mechanical self-winding movements, Calibres 1200P (hours and minutes) and the 1208P (small seconds), 2.35mm thick and set within the new Altiplano, Piaget set new records for thinnest watch within its category.

A watch for black tie events: Emperador Coussin Tourbillon Automatic

It's no coincidence that we make this recommendation for the Emperador Coussin Tourbillon as a black tie watch- it's a part of Piaget's Black Tie collection. As a mark of distinction and refinement, the Emperador Coussin offers a front view of the automatic movements. Both micro-rotor and tourbillon carriage in lucky figure 8 configuration can be seen. From laser guilloche detailing to tapered hour markers to gold rimmed oscillating weight and tourbillon displays, the Emperador Coussin Tourbillon is beautiful both inside and out. This fine timepiece is rounded off with viewing window through caseback and proudly adorned with the Piaget Coat of Arms.
