Cyrus Genève is celebrating 10 years in business, completed in 2020, with a special piece: the new Klepcys Vertical Skeleton Tourbillon Sapphire, produced in a limited series of only 10 pieces. The first edition of the Klepcys Vertical Tourbillon, animated by a highly innovative hand-wound movement, was launched in 2018. The tourbillon cage, placed for the first time in the centre of the dial, is positioned on a vertical axis inclined at an angle of 90°. Careful studies by the Cyrus technical team revealed that this angle ensures that the tourbillon cage is almost always in a vertical position when the watch is fastened to the wrist, thereby optimising its performance in terms of precision. To further emphasise the special nature of the mechanism employed, Cyrus Genève chose a skeleton architecture for the dial and adopted, for the first time in its history, a sapphire crystal case, which allows a complete view of the movement from all angles. Composed of 29 parts (the sapphire crystal components are the case body with the lugs, the bezel, the caseback ring and the two sapphire crystals on the dial and caseback), the design of the case, 44 mm in diameter, has been redesigned to conceal the fasteners, screws and steel elements from view. Some points of intersection have been slightly rounded to make machining and polishing possible without compromising the design of the watch. Making the sapphire case was a major challenge for the technicians at Cyrus Genève, as its particular shape required the use of small tools, and consequently very time-consuming machining. Polishing operations also required many hours of work before all surfaces were perfectly polished. The transparency of the case helps to highlight the curved 18K rose gold 4N bridge, inspired by Leonardo da Vinci's self-supporting bridge, which symmetrically divides the hour and minute indications. In fact, retrograde jumping hours are displayed on a black microblasted arc on the left of the dial, with luminescent Arabic numerals, while retrograde minutes are read on the right. The seconds are visible on the tourbillon cage in the form of small numbered plates scaled in 5-second intervals, while between the two arches of the tourbillon bridge, at 12 o'clock, there is a black DLC microbillé sphere with a diameter of 5 mm, which serves to indicate the days of autonomy (1 to 4). Thanks to the use of sapphire and the openworked dial, it is possible to admire the movement used, an in-house mechanical hand-wound CYR625 calibre beating at 21,600 vibrations per hour and offering a power reserve of over 100 hours. The watch is completed by a white rubber strap featuring a new raised prism motif, with a personalised 4N 18K pink gold folding clasp.
