Bridges combined with the MainplateMainplate The mainplate holds all the components of the watch movement together and forms the base of the watch movement. 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] form the very foundation of the watch movement. The bridges are used to secure wheels and various other parts in place. After the parts are placed on top of the Mainplate, the bridges are placed on top and screwed against the mainplate, thus securing everything nice and tight.

The more elements that need to be secured with a single bridgeBridges 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. Combined with the main plate they are the foundation of any watch movement. [Learn More], the more challenging it is to set it for the watchmaker.

A balance bridge, is a bridge used exclusively to secure essential bits (balance wheel & spring) of the escapementEscapement The escapement is a mechanism in a mechanical watch movement that regulates the release of energy from the mainspring and keeps the watch ticking at a steady rate. The escapement is made up of two main components: the escape wheel and the pallet fork. The escapement is responsible for the ticking sound of the watch, and it ensures that the watch runs at a consistent rate. As the escape wheel rotates forward, it locks and unlocks with the pallet fork, allowing a small amount of energy from the mainspring to be released. This causes the balance wheel to oscillate and the watch to 'tick'. [Learn More] to the mainplate.
