CYRUS Genève presents Klepcys DICE Lime, a new interpretation of its Double Independent Monopusher Chronograph.

Introduced in 2021, DICE is an acronym for Double Independent Chronograph Evolution. It is equipped with a Double Independent Monopusher Chronograph movement, developed by CYRUS in its in-house Manufacture in Le Locle. This extraordinary timepiece was developed by Jean-François Mojon, one of the talented master watchmakers in the modern era.

Like its predecessor, the new Klepcys DICE Lime is equipped with two independent monopusher chronographs for measuring two short intervals of time independently or in synchrony, all housed in a single self-winding mechanical movement.

The hallmark feature of CYRUS Genève’s KLEPCYS timepieces is the iconic cushion-shaped case with elongated lugs on the case body, a three-dimensional bezel with rounded corners, and symmetrical twin crowns. Assembly of the case is a complex process involving no less than 26 polished and satin-finish parts.

The Klepcys DICE Lime comes in two versions, crafted from natural grade 5 titanium with a polished/satin finish, or a black DLC treatment. Just 10 pieces are available for each version. Given the amount of space occupied by the unusual calibre, with two mainplates and as many chronographic modules, the size is actually limited, with a diameter of 42 mm and a thickness of 16.5 mm.

The thinner bezel has been slightly adjusted to make more room for the dial and enhance legibility. Titanium is a hard-wearing, extremely lightweight material that makes this model, waterproof to 10 ATM, extremely comfortable to wear.

The 3D architecture of the open-worked display is an emblematic feature in all the Swiss Maison’s watches. It is a meditated approach, and designed to allow the chronograph mechanism to be seen in action from the dial side, from which the two column wheels are clearly visible.

The elapsed times recorded by the two chronographs can be read off at a glance, thanks to the two-colour scheme which CYRUS Genève has adopted in dazzling green and intense yellow. Both hues feature on the two hands of the chronograph counter at 3 o’clock, on the double-scale flange around the dial, on the column wheels and the respective crowns.

The chrono minute and second hands are specular. The first chronograph is picked out in green; the crown set at 3 o’clock starts, stops and resets it to 12 o’clock. The second chronograph is set with the pusher on the crown at 9 o’clock; it is highlighted in yellow, and resets to 6 o’clock.

The open-work luminescent hands are rhodium-plated. They indicate the time on a bevelled, anti-reflective sapphire crystal ring with raised Arabic numerals, also luminescent, which emit a blue glow. The transparency also ensures an unhindered view of the breath-taking movement that powers this model. The small seconds are placed at 9, with an original hand which recalls the Maison’s logo: a three-armed helix with a luminescent tip.

The look of the Klepcys DICE Lime has received an upgrade. The chrono counter and small seconds are both crafted in anti-reflective sapphire crystal with markers and profiles in green. The bridges above the respective counters are lacquer-finished in the same shade. The colour elements are all combined with skill, making for a dial which is aesthetically pleasing.

To round off the style of the new “Klepcys DICE Green”, CYRUS Genève has opted for a green Cordura fabric strap with a titanium folding clasp to match the case. The watch is delivered with an additional soft black rubber strap.

Once again, Jean-François Mojon has surprised enthusiasts with his latest creation: the CYR718 automatic calibre. The movement which powers the Klepcys DICE Lime features two identical chronograph mechanisms which are visible on the dial side, as the movement has been reversed. The symmetrical design offers a fascinating view of the two column wheels that are the “heart” of this complication.

The two mainplates of this innovative mechanism are finished with a black micro-beaded PVD treatment. The additional module for the two independent chronographs is made up of 218 components, all mounted on the two mainplates. With 443 components in total, the mechanism beats at 28,800 vibrations/hour, and the single barrel delivers a 60-hour power reserve.

Klepcys DICE Lime is equipped with two independent chronograph movements and two display axes: one corresponds to the chronograph seconds and the second to the 30-minute counter of the double chronograph. The chronographs are activated by two column wheels, which in turn activate the different levers and couplings that move the seconds and 30-minute chronograph display.

The activation of chronograph levers generates considerable shocks and dispersion of energy, especially during the return-to-zero phase when the hammer on the heart cam is activated. Thanks to a special system of insulation, which ensures precision measurements for the duration of the event, these shocks have no repercussions on the display of the functions. In short, the two chronographs function independently without exerting any influence on one another.

The motion work mechanism that carries the hours and minutes hands also required special attention. Conventionally, this mechanism is composed of several gears placed on different rotational axes. However, to free up as much space as possible for the dual chronograph complication, Mojon came up with a concentric mechanism for the motion work. Not only is the mechanism more compact, but it is coaxial to the axes of the hands.
