Technischer Bauplan-Querschnitt

Hyper-detailed technical cross-section cutaway diagram of a [mechanical wristwatch], rendered in a dark engineering blueprint style mixed with photorealistic rendering. The cutaway reveals internal components, layered assemblies, and precision mechanisms. Every part is labeled with clean white annotation leader lines, callout text boxes, and technical measurements. Includes a bold title header at the top, a materials and components legend, dimensional specifications, and small detail inset boxes showing magnified close-up views of key sections. Dense, information-rich composition with no empty space.
