Kerbedanz Maximus, the world’s largest tourbillon in a wristwatch

A Kerbedanz world premiere in a limited edition of 99 pieces Maximus, the world’s largest tourbillon cage measures 27 millimeters across. The Maximus masterpiece of horological micromechanics was introduced to the media and all the world’s buyers at the end of March at the Baselworld trade fair. An unusual timepiece that breaks the mold.

With its 27-millimeter cage, which is almost twice the size of the largest one known to date, the biggest wristwatch with tourbillion in the world, by Kerbedanz, couldn’t be called anything but Maximus. Indeed, the most imposing monument of all of Roman Antiquity is still in Rome to this day and is called the Circus Maximus in Latin and in Italian. This famous venue was used for horse-drawn chariot races. It was built between the Palatine and Aventine Hills in the early 6th century B.C.E. by the Etruscan king, Tarquin the Elder.

Quintessential complication meets chronometric science This unbelievable watch, which transcends this seminal complication in a technically impeccable and visually most spectacular manner, represents a watershed in the story of this top-flight brand, Kerbedanz, which has been winning over more and more informed collectors and MIP – most important personalities – from its home base in Neuchâtel, Switzerland. This term, in contrast with the hyped term, is a discreet reference to the fact that the brand’s customers include individuals who have the most influence in the world, like statesmen and – women, in other words, people with power and influence. It’s an important watershed because until now, Kerbedanz revealed its multiple crafts inherited from a long family tradition in the field of jewelry in the extreme luxuriance of its dial decoration, which always features a host of allegories and initiation journeys combined with stylistic civilizational references to history. All those limited editions or unique pieces might easily conceal the fact that the brand also integrates the quintessence of the art of traditional Swiss horological complication, and that it is able to develop the most complex products using the science of chronometry. The tourbillon was invented by the great watchmaker Abraham Louis Breguet (1747- 1823. The complication places the regulating organ of the watch inside a cage that turns on itself, thus varying the position of the regulating elements to compensate for errors due to gravitational forces, to non-concentric development of the balance spring, and the point where it is attached to the collet. In watchmaking, enlarging the size of certain components does not mean just multiplying their size. Everything needs to be reinvented, recomputed. Two patents are pending.

Symbolism that serves an ultimate caliber

Not only does the Maximus flying tourbillon by Kerbedanz allow one to better observe and understand the subtleties of this fascinating mechanism, thanks to its sheer size, but it also demonstrate the extent of the company’s watchmaking competencies: This watch required conception and manufacturing of a special balance spring, a rack with a screw for fine adjustment, and a balance wheel. The cage of this watch makes a full rotation once every six minutes, and not in sixty seconds, which is usually the case. In terms of energy, the Caliber KRB-08, with its giant central flying tourbillon, in-line pallets, and 27-millimeter cage, boasts four parallel barrel springs that drive a central wheel mounted on ball-bearings. This produces enough power for a tourbillon of such size. It runs at a frequency of 2.5 Hertz, or 18,000 vibrations per hour. The feat lies in being able to develop a power reserve of 48 hours, which is displayed on a separate indicator. The watch is made up of 415 carefully assembled components, of which 73 are dedicated to the tourbillon cage. The latter is made entirely of titanium and only weighs 1.35 grams. Achieving such perfection requires the expert hands of select watchmakers.

Giving meaning to beauty

At Baselworld 2017, the beauty shown by Kerbedanz by the world debut of the Maximus is not only symbolic. It has all the esthetic opulence emanating from meticulous watchmaking balance and scrupulous finishing, like the superb hand-polished beveling, the drawing of the watch’s flanks, the circular-grained wheels, or the mirrorpolished screws. As for the name Maximus, it has a long pedigree and is also steeped in allegorical meaning. It not only celebrates the high priest at the head of the College of Pontiffs, the religious figures at the heart of Rome’s state religion who were in charge of the calendar that indicated propitious and unpropitious days, of consecrating buildings, naming other priests, like the flamines and the vestal virgins, and maintaining the Roman archives containing the notable events in the “Great Annals.” Maximus was also the title granted systematically to all the Roman emperors during the period following the reign of Augustus. Maximus, in antiquity, was a key word wherever grandeur and splendor were being expressed. In 2017, the term has taken on a new, masterly dimension, one made up of a respect for watchmaking fundamentals, combined with a bold quest for watchmaking excellence. A significant opus, and an inescapable one as well.
