Table clock NT 12

A powerhouse with long power reserve

The table clock NT 12 is another proof that the mechanics of clockmaking are limitless. At our Naeschke clockworks we constantly aspire to implement new ideas into the design of our clocks. The results are luxurious and bespoke timepieces that excite passion and engagement for professionals and clock aficionados alike. The table clock NT 12 is no exception.

The movement is a real powerhouse. Two weighty barrels together provide nearly 20kgs of spring force that pull on a single steel wire of just one millimetre diameter. Thus the entire power is transmitted to the fusee and through it to the going train. A conventional fusee chain would not withstand this enormous force and would be prone to breakage.

Beautifully finished mechanics

So why does the NT 12 require so much more energy than similar spring-driven movements? This is due to the considerable running time of one year. The wheels and the entire frame of this clock have been proportionally sized for this purpose. The pillars which connect the main plates to each other are positioned so that there may be no distortion. Much of the beautifully finished gilded mechanism is visible through its creative design and arrangement.

The movement sits on four solid columns forming a platform. Of the two integrated barrels only one is visible. It is separated from the gear train and is placed centrally at the foot of the columns whilst the other barrel is concealed in the base of the clock. In addition to the time display on a sterling silver dial the NT 12 also has a separately presented power reserve indicator.


Long runner with larger sized details

All parts are dimensioned slightly larger in this clock as is the winding key which is a perfectly proportional match. It was formed by us so that it is most pleasing and comfortable in the hand. To celebrate the pleasure of handling the key after a full year it was allotted a separate drawer in the wooden base of the case. What a pity that this magnificent clock needs truly little compassion.
