3d-printed watch with Tourbillon

This video shows how my 3d-printed watch works and how it was designed and constructed…

The developer of the 3D-printed watch, explains:

“This is a mechanical watch with tourbillon and going barrel. The watch has a Swiss lever escapement, embedded in the tourbillon. It is driven by a 3d-printed spring, and runs 35 Minutes (a wire retraction spring made from steel would perform better). My watch is running with less than 0.5 Seconds deviation within one Minute.

The project demonstrates that the 3D-printing technology is developing. Compared with earlier generations of 3d-printers, the process works more reliable and more accurately.”
