Making watch gears

Watches have small components with details often only visible under the microscope. Those tiny gears, springs, caps and holes are laser cut by an ultrashort pulse laser. A laser machine can produce very quickly all the parts a watch needs, so the material cost of the watch stays low. However, this is an application area where an affordable laser will likely not reduce the prices.

But watches are not the only products using tiny mechanics: high quality slits, grids for electron microscopes or sim card tools are examples of such use cases.

Lasea produces laser machines and has a very good showroom of these watch parts. It’s worth checking out their website:
