Developed with the help of watchmaker Eric Coudray in 75 numbered examples, this masterpiece of intricacy is made up of 90 parts for a total incredible lightweight of 0.336 grams.

Its constructions involves two diferent cages: an interior cage to which the balance wheel is attached that revolves once every 2.5 minutes, and an exterior one revolving around an axis perpendicular to that of the frst one which revolves once per minute. While the Gyrotourbillon is undeniably the “star” of the watch, this piece has even more to ofer, bearing also a perpetual calendar devised in an extremely unusual way, and an equation of time indication. The perpetual calendar displays informations on both sides of the watch. On the dial side, month and day are displayed in retrograde fashion. On the movement side, a brushed skeletonize subsidiary dial displays the day of the week; the leap year indication is present as well, retrogradely displayed. Finally, the a sidereal hands on the main dial indicates the equation of time (deviation of solar time - the time that would be indicated by a sundial - from the normal standardized time). Intriguingly, the attention to detail of Jaeger-leCoultre was so extreme that each equation of time is set to the owners country of residency. In this case Kuwait, which has a maximum deviation of 12 minutes, as described by a plaque applied to the movement.
