Kerbedanz Maximus
Description
Unlike other tourbillons, which require the use of a bent anchor escapement for space reasons, MAXIMUS, with its cage diameter of 27 millimeters, allows the use of a straight-line pallet (straight stem). This helps to achieve better performance, as the energy loss with a straight-line pallet is significantly less than with a bent one. The gigantic size of the MAXIMUS tourbillon and its central position in the middle of the dial, curved in the shape of an amphitheater, and dominated by an immense transparent sapphire dome, allow the owner to well observe and better understand its operation.
The design, creation, adaptation and perfect integration of this gigantic MAXIMUS tourbillon into movement, the dial and the case of the watch made a phenomenal technological challenge for KERBEDANZ, perfectly keeping the traditions of fine watchmaking.
When viewed from the dial side, the tourbillon cage is fully exposed and the observer’s eye can follow the oscillations of the escapement regulator system, as well as the complete rotation of the tourbillon, which, due to the unprecedented dimension of the cage, is slowed down to six minutes (instead of one minute for standard tourbillons). This slowdown in cage rotation is obtained due to an additional wheel or a reversing wheel - visible in the cage - which meshes with the pinion of the escapement wheel. The two discs of hours and minutes are also visible, with their respective hands attached thereto. These two hands have been designed and made in a special way. Afterwards, they were hand curved to perfectly match the specific shape of the twelve indexes, reminiscent of the access doors to the bleachers that surrounded the arena of Roman amphitheaters. The gigantic transparent sapphire crystal, with anti-reflective coating, displaying and protecting the dial and the tourbillon, has been conceived as a true dome, the inner concave shape of which is in parallel with the outer convexity. This allows to leave sufficient space to accommodate the height of the tourbillon, but at the same time to reduce the height of the case middle, for obvious aesthetic reasons. The case middle, which represents the profile of the watch, carries a vertical fluted decoration, alluding to the colonnades and arcaded openings of the exterior masonry of the circuses and theaters of ancient Rome. The MAXIMUS case back is particularly original in its design due to the fact that it features a winding mechanism of an unprecedented shape above the transparent sapphire crystal. This transparent anti-reflective crystal provides a glimpse of the four barrels placed in parallel to move a central toothed wheel, mounted on ball bearings – the assembly providing the torque necessary to supply energy to the moving parts to be moved that comprise the oversized tourbillon and the 40 millimeter diameter mechanical movement. The gears have been reinforced and sized so that they can withstand very high torque loads.
The “gauge” indicating the power reserve of more than 54 hours is also displayed on the case back rather than on the dial – which is logical, given that the winding of the movement by the four barrels is carried out from the case back by means of a very special winding mechanism, independent of the crown – the latter being used only for setting the time.
The force required to wind the four barrels is such that it required the design of a manual winding system through the case back, actuating the central ball-bearing gear wheel, which itself meshes with the barrel wheels. The winding "key" is designed like a sort of octopus or spider, not with eight legs, but with six "arms" that are hooked with the fingers to turn them clockwise. Winding is done by a ratchet system, the latter is designed with a clutch to prevent a ratchet or tooth from breaking in the event of an error in the direction of rotation. The exceptional MAXIMUS movement was designed, manufactured and decorated by KERBEDANZ. Mechanical with manual winding, it comprises a total of 415 components. Among these components, 73 constitute the tourbillon and its cage, entirely crafted in titanium, weighing 1.35 grams. The height of the movement itself reaches 8.35 millimeters and 13.2 millimeters with the tourbillon cage. It was also necessary to master the design and manufacture of the balance, the balance spring, and the index assembly with fine adjustment screws.
