This year at Baselworld 2014, Breguet introduced eight new timepieces including the new ref. 5377 Extra-Thin Tourbillon Automatique available in either 18K rose gold ref. 5377BR/12/9WU or in platinum ref. 5377PT/12/9WU. Today, we bring you our hands-on review of this exceptional timepiece with these incredible images under natural light that we captured just for you. This new extra-thin tourbillon has already been included in the pre-selection for the 2014 Grand Prix d'Horlogerie de Genève here and is now regarded as the world's thinnest automatic tourbillon movement. This new watch featuring all the traditional Breguet elements, seems to be one of the top contenders for one of the prizes to be awarded on October 31st at the Grand Théâtre de Genève. As you all know, Abraham-Louis Breguet was the father of the tourbillon in 1795, and this watch honors his groundbreaking creation in a flawless manner.
