The Swiss micro-manufacture Cyrus is named for Cyrus the Great, a king of ancient Babylon, and its watches are distinguished by replicas, imprinted on the casebacks, of a 2,500-year old Babylonian coin, one of the world’s first currencies. Designed by Swiss watchmaker Jean-François Mojon — who masterminded the Harry Winston Opus X and collaborated with Kari Voutilainen on the MB&F LM1 movement — Cyrus’s lineup of high-complication, limited-edition timepieces includes chronographs, moon-phases, mechanical alarms (you can read a review of the Klepcys Réveil here), and, most recently, the innovative Klepcys Vertical Skeleton Tourbillon, unveiled at Baselworld 2019 and set to wow U.S. watch aficionados at the upcoming WatchTime New York collectors event on October 25-26. Here are the details.

The Cyrus Klepcys Vertical Skeleton Tourbillon follows up the groundbreaking original Vertical Tourbillon, introduced last year, which placed the tourbillon cage in the middle of the watch’s dial, on a vertical axis and inclined at a 90ª angle — according to Cyrus’s technical researchers, the angle at which the tourbillon is almost always in a vertical position on the wrist. In the new openworked version of the movement, the wearer is afforded a clear view into the heart of the watch, including the rhythmic rotations of the tourbillon, while reading the time off of two retrograde hands. The timepiece’s symmetrical 3D architecture is built around an arched vertical bridge — inspired, Cyrus says, by the designs of Leonardo Da Vinci, and decorated in the “microbillage” technique — that frames the tourbillon cage and divides the dial into two equal parts, each with a numbered scale on its border.
On the right side is a 0-to-60 arch in microbrillage-decorated black DLC for the minutes, on the left a similar scale, with white Arabic numerals from 1 to 12, for the jumping hours. Together, both displays indicate the time on sculpted retrograde hand, while the running seconds are read off the tiny numbered blocks on the tourbillon itself, which makes a rotation on its axis every 60 seconds. A bonus complication can be found at 12 o’clock: a black DLC microbillé sphere displaying the days in the watch’s power reserve (1 through 4). This element is balanced out, and the watch’s symmetry preserved, by the applied Cyrus logo at 6 o’clock. The cushion-shaped case, measuring a stately 44 mm, is also visually balanced by two parallel crowns, set at 3 o’clock and 9 o’clock. The 3 o’clock crown sets the time and winds the movement while the one at 9 o’clock serves as a push-button to rapidly correct the hour hand.
The manually wound movement, Cyrus Caliber CYR625, is visible from the back as well as the front, beneath a sapphire caseback. Its haute horlogerie decorations include the curving sunray pattern on the bridges, which also boast a gray NAC galvanic treatment, a microbillé satin finish, and beveled and polished edges. The wheels are rhodium-plated and enhanced with cerclage, the cams are mirror-polished, and the levers of the retrograde system feature both satin polishing and rhodium plating. The two parallel mainspring barrels, which store the aforementioned 100-hour (four-day) power reserve, are topped with black-lacquered ratchet wheels adorned with Cyrus’s propellor-like logo.
The Cyrus Klepcys Vertical Skeleton Tourbillon is available in three versions, each strictly limited to five pieces: one in titanium with black DLC (pictured), a second in 4N rose gold, and a third combining rose gold with black DLC. The DLC and two-tone models come on black alligator straps with titanium clasps, the rose gold model on a brown alligator strap with matching rose gold clasp.
