Founded in 2010, CYRUS Genève turned 10 in 2020. To celebrate this important milestone, the Swiss Manufacture has created a limited series of 10 pieces. Due to the current global pandemic and as it happened also for the Olympic Games in Tokyo, we are able to unveil the new KLEPCYS VERTICAL SKELETON TOURBILLON SAPPHIRE one year later.

Designed by master-watchmaker Jean-François Mojon, the brilliant creative mind behind all Cyrus creations, the first edition of the Klepcys Vertical Tourbillon was released in 2018 and showcases an outstandingly innovative manual winding movement driving the watch. The tourbillon cage, placed in the middle of the dial for the first time, is set on a vertical axis at a 90° angle. Painstaking studies by the technical team at CYRUS revealed that this angle ensures the tourbillon cage is almost always in vertical position when on the wrist, thereby optimizing its performance in precision.

To further enhance the beauty of this surprising mechanism, Cyrus Genève chooses a unique 3-D open-worked architecture for its dial and adopts, for the first time, a transparent sapphire crystal case which allows a complete view of the movement from all angles and let watch enthusiasts and collectors appreciate all its stunning details.

Composed of a total of 29 parts (the sapphire crystal components are the case body with lugs, the bezel, the case back ring and the two sapphire glasses on the dial and on the back side) the style of the 44 mm case, excluding the functional 18k 4N rose gold twin-crowns, has been redesigned to hide a maximum of fasteners, screws and steel elements. Some recessed edges have been slightly rounded to make machining and polishing possible without compromising on design and the strong character of this watch.

The realization of this sapphire crystal case with the intricate geometry of the Klepcys Tourbillon model was a very big challenge. Complex shapes required the use of small tools, which generate very long machining. Polishing operations also needed many hours of work before all surfaces were perfectly polished and free from surface defects. It goes without saying that by the very hard nature of sapphire, the edges can crumble under the pressure of the tools and then you have to restart from the beginning.

The result is a feeling of lightness of this timepiece while guaranteeing tested resistance 
to any wearing conditions.

The transparency of the case contributes to highlight the 18K 4N gold arch, inspired by Leonardo da Vinci’s self-supporting bridge, which simmetrically divides the hours and minutes indications. Due to this lay-out, the KLEPCYS VERTICAL SKELETON TOURBILLON SAPPHIRE shows the jumping retrograde hours on a left black microbeaded arch with luminescent Arabic numerals while the sweeping retrogade minutes are read off on the right arch. Hour and minute hands are also covered with Super-LumiNova for better legibility in dark light conditions. The seconds are visible on the tourbillon cage thanks to small numbered plates on a 5- second interval scale.

Between the two arches of the tourbillon bridge, a black DLC microbillé sphere with a 5mm diameter, set at 12 o’clock, catches the eye. It displays the days of the power reserve (1-4). To achieve a balanced effect, the CYRUS logo is set at 6 o’clock. This original 3D structure is protected by a tailor-made sapphire crystal glass which is domed and anti-reflective, with a thickness of 1.2 mm.

Thanks to its transparent nature and exclusive open-worked dial, all the features of the in-house manufacture hand-wound movement, caliber CYR625, beating at 21.600 vph and offering over 100-hour power reserve, can be admired in full.

The “beating heart” of the KLEPCYS VERTICAL SKELETON TOURBILLON SAPPHIRE can also be seen from the case back. This reveals the masterful finish executed by the highly skilled master artisans at CYRUS Genève. The grey-colored bridges, thanks to the NAC galvanic treatment, are decorated with embossed sun-ray pattern and have a micro-beaded satin finish that contrasts with the polished finish of the edges.

The two parallel barrels have black lacquered ratchet-wheels adorned with CYRUS’s signature propeller-like logo. The sapphire crystal ring which secures the case back with customized screws, is engraved with the inscription “10 years CYRUS - Est. 2010”.

This new timepiece is completed with a white rubber strap featuring a new embossed prism pattern and is fitted with a 18K 4N gold folding buckle embellished with the CYRUS logo.

As you all know by now I love watches that constantly push the envelope of design and engineering, Cyrus did all that and then some! The sapphire case in and of itself is a technical marvel, coupling this with the tourbillon cage and attention to detail and precision "as with all Cyrus watches" is unbelievable!
