Watch Bridge: A Crucial Watch Part
What exactly is a watch bridge? Well, the typical definition of this vital watch part states: a bridge is a complementary part fixed to the main plate to form the frame of a watch movement. However, if you’re not really familiar with watch terminology and parts, this definition may not be incredibly helpful to you.
Note: Something important to remember about a bridge—DON’T touch it. In fact, don’t touch the bridges or wheels of any automatic watch with your fingers. The oil from your fingers can actually rust the parts and etch the plates of the movement. Going along with that, don’t blow on the movement either. It could add moisture that would also lead to unwanted rusting.
