Why is the Naeschke workshop always looking for new challenges? Sounding out the frontiers of physics and translating the results into harmonious objects is without question a wonderful task.
The fascination of mechanics really begins on its boundaries. It is usually a question of the boundaries of stability, of the largest and the tiniest of forces, of miniaturisation or of the greatest or the slowest of speeds. Venturing into realms such as these was always the great challenge for clockmakers. A typical case of this was the one-year precision clock, which was invented 150 years ago.
However, one challenge that had never been accomplished was to design a four-year clock. Far beyond the efficiency this brings, this clock is an expression of our times. It needs very little care or attention. It will prompt its owners daily to think about their relationship to time.
The development of this four-year clock is based on the experience in the Naeschke workshop of building a total of 75 one-year clocks. The result is an extremely robust and durable clock – and a remarkably beautiful clock of harmonious design. There is nothing and has never been anything comparable.
The enormous power, this clock needs to be driven, was the biggest challenge for Matthias Naeschke.
Here, seven wheels run in ruby or ball bearings between 6-mm thick plates. Two independent main and intermediate wheels transmit their rotation to a common third intermediate wheel. This construction, which was devised in the Naeschke workshop, permits the use of normal clock wheels, even for the great wheel. And thus the energy needed is halved. This is the basic concept behind the four-year clock.
For the escapement, we have again used the proven dead beat escapement with round ruby pallets.
The precision of the craftsman’s skills is taken to extremes in this clock: every single escape wheel is very finely balanced in a special device. Any imbalance in the wheel is eliminated by means of fine vertical drill holes at the base of the teeth.
The regulator is a compensation pendulum which was also completely developed by Matthias Naeschke. In the meantime it has been successfully used in various different clocks. Three different materials work together in this 5-rod compensation pendulum.
The case is very sturdy and torsion-free, to be able to withstand the great forces and weights involved. It is made of dark stained cherry wood, but still looks light and delicate. Silver strips surround the three-faceted glass. The clock conveys an impression of timelessness, and at the same time is reminiscent of the Empire style.
