Taking its innovative concept another radical step further, Cvstos once again rises magnificently to the challenge of complexity by combining two particularly ingenious watchmaking complications within the same timepiece, the Minute Repeater and the Tourbillon. In a superlative demonstration of watchmaking mastery cloaked in supreme modernity, the Challenge RMT-S adds a new dimension to two watchmaking complications that require rare skill and genius. The sapphire crystal dial and crystal back leave open to view and admiration the sophisticated workings of an openwork movement in which Minute Repeater and flying Tourbillon perform an exquisite mechanical ballet. In an extraordinary illustration of the fine art of watchmaking, simply by pressing the push-piece at 9 o'clock the wearer can instantly change time into music. The meticulously arranged components inside the case create the perfect chamber for the crystal-pure resonance of a movement that chimes the hours, quarters and minutes on demand. A safety device indicating the operation of the movement helps prevent any false maneuvers that might damage the functioning of this complex mechanism. The seconds are marked out in an animated display consigned to the upper bridge of the flying Tourbillon cage. This tremendous feat of watchmaking engineering crafted in flaming red anodized aluminum takes on its full meaning as it completes its journey of the "3 X 20 Seconds" counter encircling the ingenious mechanism. Sculpted in titanium, the tonneau-shaped case makes a firm statement in an impressive architectural array of bold, contrasting volumes. Alternating polished and satin-finished surfaces enhance the pronounced curve of the case to perfection. Water-resistant to a depth of 100 meters, this exceptional timepiece is fitted with an alligator skin or black rubber strap with folding clasp. Featuring a sporty design with an avant-garde twist, the RMT-S with manual winding captures all the essence of a masterpiece of traditional high-end watchmaking. With this spectacular accomplishment, the jewel in the Concept-S crown, Cvstos is firmly ensconced in the elite world of Swiss Haute Horlogerie.
