The Gruebel Forsey Quadruple Tourbillon possesses not one, but four tourbillons within one 43.5mm wristwatch – a feat of engineering so impressive it is beyond belief. Released in 2009, the advanced engineering of the watch allows supreme accuracy, varying by less than 2.5 seconds per day. The movement in its entirety features 534 individual parts, most hand-finished by a team of artisans, including 261 parts solely for the four tourbillon cages. Not only is the movement absolute mastery, but the case and dial are executed and finished to the highest standards as well. The dial is silvered gold, with sapphire apertures at the sides of the asymmetrical case in order to view the tourbillon at work.

In a 2015 New York Times article, Stephen Forsey was quoted as saying the driving principle in creating the Quadruple Tourbillon was “about ‘refusing to accept that everything had been achieved in terms of the mechanical watch.” To behold this masterpiece through the dial, caseback, or lateral openings is to view the encapsulation of one entire year of man hours, the accomplishment of 8,760 hours of meticulous handiwork. This is an incredibly special piece by a manufacture on the cutting edge of haute horologie.
