At the crossroads between technical accomplishment and aesthetic boldness, Chopard introduces the L.U.C Tourbillon Tech Twist with a “Winding Assistance System”. This unprecedented winding system specially developed for this new timepiece is a world-first invention. With its unusually oriented movement and its four barrels, this model naturally commands respect, both for its technical qualities and for the originality of this unusual layout. Chopard is thereby enriching the Twist line with a premium complication: the tourbillon. The L.U.C Tourbillon Tech Twist is issued in a limited edition of 100.The L.U.C Tourbillon Tech Twist was designed around a skilfully mastered reinterpretation of the way displays are traditionally oriented – along one vertical axis and another horizontal one. It thus embodies the contemporary essence of the Twist concept, which Chopard Manufacture incorporates in this case into the Tech line – best known for its focus on technical elements. The L.U.C Tourbillon Tech Twist thereby boasts a perfect blend of originality and horological creativity.
With its aluminium carriage, an exclusive Chopard signature feature, the tourbillon elegantly positioned at 7 o’clock sets the pace and displays the seconds by means of an arrow-shaped blued steel hand. The ethereal appearance of this tourbillon is further accentuated by its bridge hollowed to form the arc of a circle. Just opposite at 1 o’clock, the power-reserve indication echoes this spectacular complication by showing the remaining energy available on another arc of a circle. Two horizontal wave-shaped lines complete this geometrical arrangement, creating an overall harmoniously gentle visual effect. The latter is further accentuated by the Arabic numerals appearing only the upper part of the dial so as to leave more scope for the tourbillon in the lower part. The extensively unveiled bridges of the exclusive L.U.C 4TBST movement are adorned with slender “Côtes de Genève”.
Endowed with the exclusive L.U.C “Quattro”® technology based on two sets of two stacked barrels, the proprietary hand-wound L.U.C 4TBST movement guarantees an almost 9-day power reserve. Chronometer-certified by the COSC, a reliable token of precision, this calibre is equipped with a Chopard-patented Variner® balance enabling fine adjustment.
It is housed within an 18-carat white gold case measuring 42 mm in diameter and fitted with a sapphire crystal and case-back featuring a glare-resistant treatment on both sides.
The W.A.S. device The 18-carat white gold crown at 4 o’clock bears the L.U.C logo characterising the collection and is equipped with the W.A.S. device – the main element in the winding assistance system specially developed for this model. The L.U.C logo on the crown is depressed to enable the user to apply the tiny “crank handle” serving to wind the movement. The latter, together with the crank handle, comprises 24 separate parts, including some in gold. Finally, the “twisted” movement of the L.U.C Tourbillon Tech Twist places the crown at 4 o’clock, ensuring ideal comfort on the wrist. The hand-sewn crocodile leather strap is fitted with an 18-carat white gold folding clasp. This eminent example of Haute Horlogerie is crafted in a limited series of 100.
