A round brass main plate with a gold finish, a balance wheel with hairspring and a jewelled pallet fork, an escape wheel, a stack of gear train wheels of different sizes with fine teeth, a barrel with a visible mainspring, bridges held with tiny blued steel screws, and red ruby jewels in polished gold chatons. A ring-shaped steel case edge and a crown. Rich metallic materials: gold, steel, bright red rubies, blued screws.
