Top 10 Thinnest Mechanical Wristwatches: 8 Modern Record Holders And Their 2 Historic Rivals

Piaget was the undeniable champion in this field with the release of Caliber 9P in 1957 - the thinnest manually wound movement, only 2 mm in height - and the Caliber 12P in 1960, the thinnest automatic movement, only 2.3 mm in height To celebrate the awesomazingness of these watches, I've compiled a list of the 10 thinnest mechanical watches, including a pair of historical pieces that provide context for what brands are producing today For a watch and movement debuting exactly 60 years ago, the fact that it makes the top ten thinnest watches list in 2020 means it is one of the most ahead-of-its-time pieces of the twentieth century.

The Bulgari Octo Finissimo Tourbillon Automatic claimed the title for thinnest automatic watch, thinnest tourbillon, and thinnest automatic tourbillon - and very possibly ticked off Piaget to round things off Caliber 9P was often housed in thicker cases, but the impressive feat of creating a manual winding movement only 2 mm in thickness kept Piaget in the lead for thinnest mechanical movement until a few years later, when Jaeger-LeCoultre Caliber 839 was released in 1962 at just 1.85 mm Despite being the origin of ultra-thin for Piaget, the 9P still couldn't pass our number three, the modern Piaget Altiplano 900P, which became the thinnest mechanical watch in the world when it arrived in late 2013.

This granted the Ultra-Thin Squelette the title of thinnest mechanical watch in the world and provides Jaeger-LeCoultre two spots in the top six thinnest mechanical watches of all time - while the battle rages on between Piaget and Bulgari. . Source
