Watchmaking: Machining a 0.6 mm Screw

The video tutorial demonstrates the process of machining a 0.6mm diameter screw for a watch using a watchmaker's lathe. It covers the selection of materials, initial machining, thread cutting, and finalizing the screw. The tutorial emphasizes the precision required at this scale and provides insights into the challenges faced in watchmaking, such as losing small components and ensuring the accuracy of threads. The video concludes by placing the process in the broader context of watchmaking and hints at future content on screw hardening and bluing.
