ENGINEERING PROWESS WITH ARTISANAL PERFECTION
The lining burin resembles a flat burin, but its cutting edge has sharp teeth. To execute the tremblage on the dial of the ZEITWERK HANDWERKSKUNST presented in 2012, the engraver manually guides the custom-crafted lining burin across the black-rhodiumed white gold in different directions. The lavish finissage underscores the technical sophistication of the digital jumping numerals display.
A special feature of the watch presented in a limited edition of 30 pieces is that the lever and escape wheel are made of hardened 18-carat gold according to a historic role model, the so-called Glashütte lever escapement. The material was chosen because it is insensitive to magnetic fields; common present-day antimagnetic steel alloys did not yet exist in the 19th century. The covered pallets are slightly domed and reduce the friction between them and the escape wheel.
