Smartwatch Anatomy Explained

Please generate a high-quality educational science illustration/knowledge card about "{......}".         
The image must show the overall appearance, internal structure, key components, material features, and working principle of the item, clearly marked in Chinese Simplified.

Overall style requirements: modern technology, teaching infographic style, clear and clean, professional and attractive, easy to read and understand, suitable for classroom presentations, popular science articles, self-media illustrations, and knowledge cards. The background is simple, using white, light gray, or light blue-gray, with a design that is rich in information but not cluttered.

Chinese font requirements:
All text must use clear, neat, and standard Chinese Simplified fonts, with styles close to Siyuan Hei / Pingfang / Microsoft YaHei / Heiti, avoiding cursive, handwriting, WordArt, and overly fine fonts.
The title text should be prominent, bold, and easy to read; The text annotations in the main text should be clear and visible, with moderate font size and high contrast, avoiding being too small, blurry, distorted, overlapping, garbled, or hard to read.
All Chinese labels, descriptions, titles, and flowchart text must be accurate, standardized, and clearly legible, suitable for print-grade knowledge cards and high-definition popular science posters.

Recommended content includes:

Main Exterior Image: Displays the complete shape of the item and marks the main external structure.
Exploded view / teardown view: Layer up the core components and their connections.
Sectional view / half-sectional view: shows the internal layout and key structural locations.
Local enlarged image: zoom in on 3–5 key details with brief Chinese descriptions.
Function description area: Use small icons + brief text to explain the main components' functions.
Working principle flowchart: Use arrows to display the basic operating logic, such as "Energy input → control system → core components operation → output results."

Key Requirements:

Chinese annotation is standardized and clear
Accurate structure and clear layering
Clear material performance (such as metal, plastic, glass, rubber, composites, etc.)
The visuals are more beautiful, more sophisticated, and more communicative
Avoid excessive artistry and flashy clutter, prioritizing accuracy, clarity, and clarity

The final effect resembles a high-quality science popularization poster / product structure diagram / knowledge card.
