PerlagePerlage Perlage is a decorative technique used in the finishing of mechanical watch movements. It is a type of circular graining that involves making small, circular marks on the surface of various movement components, such as the main plate, bridges, and gears, using a specialized tool. The marks are arranged in a uniform pattern and are typically very small and closely spaced. This technique is used to enhance the aesthetic of the movement and it also helps to protect the movement from dust, dirt, and other debris.

The mainplate is typically made of brass. It serves as the foundation for the movement, and all the gears, wheels, and other components are attached to it. It holds the jewels and pivots in place, and also serves as the base for the bridges and other structural components. [Learn More], bridgesBridges The bridges of a watch movement are the metal plates that hold the wheels and other components of the movement in place. They are attached to the main plate of the movement with screws. Bridges are used to support the balance wheel, the escapement, the mainspring barrel and other elements.
