Skeleton Movement
A skeleton movement has had a cutting away of any non-essential metal on the bridge, plate, wheel train or other mechanical part.
This leaves just a minimalist ‘bare’ skeleton of the movement necessary for operation. The remaining thinned movement is often decorated with engraving.
Watches which this type of movement usually have a sapphire crystal case back to view the movement from the back and part or all of the dial removed.
