8-Day movement - Part II

Updated: Feb 9

Location: Zurich, Switzerland

Date: May 24, 1996

The 8-Day power reserve movement served many of Paul Gerber’s own branded table clocks as well as highly jeweled timepieces manufactured in collaboration with italian jeweler Gerd Dorschfeldt as a robust and precise power engine.

Let’s take a closer look to the fabrication of the top balance-endpieces or cock endstones and the indexes.

The index was cut out using the pantograph with a 10:1 model. The position of the pins which embrace the spring is on one arm and the other, longer arm, is used as a pointer which can be moved over a graduated scale.

The brass components were turned using a Schaublin 70 lathe, beveled and finally gold plated. All steel components were hardened and the surfaces mirror polished.

The final touch, the «Côtes de Genève» finishing on the upper surface of the three bridges was made on the Aciera F1.

Most important to every new movement project is the reliability, the quality and good performance of the final work. A good base of movement prevents from unexpected and sudden defects and reflects a long term oriented business model!
