The new ZEITWERK – Making-of
Snapshots of the assembly of our mechanical digital watch
In developing the ZEITWERK, we had to break away from many conventions – and think watchmaking in a new way. Just as unusual as this watch are the people who craft it. A small team of predominantly younger, particularly talented watchmakers has specialised in this completely new watch concept. In the following, we accompany our watchmaker Sindy during selected characteristic assembly steps of the watch.
Inserting the mainspring barrel
The new ZEITWERK has a doubled power reserve of 72 hours. This is made possible by the patented mainspring barrel inserted here.
Lever for hour switching process
A new function makes it possible to advance the time display in hourly steps. Here you can see the assembly of the corresponding levers.
Inserting the jumping numerals module
The new model also uses the patented jumping numerals mechanism in the same proven way. Here, the entire module is mounted.
Third wheel with blued retension spring
The constant-force escapement, with its blued intermediate mainspring, sets the rhythm for the jumping numerals mechanism.

The exact time for the switching impulse after every 60 seconds must be set very precisely.
Fixing the balance cock with blued screw
Like every Lange watch, the ZEITWERK is assembled twice. Here, the final fixing of the balance cock with a blued screw is shown.
Viewing the finished piece
After many weeks of concentrated, precise work, the ZEITWERK is ready to make a customer happy.
