# Watch movement anatomy > An interactive isometric watch movement explains winding, the escapement and gear ratios. Ryan made it with Claude Code and the Anatomy skill from one published prompt. - Kind: Interactive reference - Live interactive reference: https://skills.wheresryan.sh/anatomy/collection/watch - Page: https://meetreference.com/v/x-watch-movement-anatomy-913394/ - Ready-to-use agent handoff: https://meetreference.com/v/x-watch-movement-anatomy-913394/agent.txt - Exact prompt as plain text: https://meetreference.com/v/x-watch-movement-anatomy-913394/prompt.txt - Authorship: AI-made, per the source - Made with: Claude Code - Model: not stated - Built with: SVG - Skills or plugins: Anatomy - Style: Interactive explainers; minimalist, technical illustration, monochrome, documentation, generous whitespace, classical art - Preview: a flip-through of inspected screenshots; open the live work to experience its motion and interactions. - Shared by Ryan in X, Oct 11, 2026: https://x.com/dingyi/status/2109163115627913394 - Prompt fidelity: Verbatim. This is the complete prompt exactly as the creator published it. ## Before you start Guidance from Reference, separate from the creator's instructions. 1. Read the reference and inspect the project, installed libraries, and available agent skills before writing code. Reuse suitable tools already present. 2. Prefer the creator-reported libraries and skills when they fit the task. Explain what useful additions help with, and install missing project dependencies or relevant skills from official sources when the environment and the user's existing permissions allow it. Respect the project's package manager and setup rules; do not ask again for routine setup already authorized. 3. Distinguish tools used by the creator from your own recommendations. A listed tool is not automatically required, and an empty tools or requirements list means the setup is unknown, not that nothing is needed. 4. Ask concise questions when missing inputs or choices materially affect the result: paid services, credentials, the user's assets, or a different production approach. Use existing answers and permissions; continue independent work while waiting. 5. If a useful library, skill, or service cannot be installed or used, explain an available alternative and its expected effect on quality, features, or effort. Get the user's choice before a material compromise; otherwise state the fallback and continue. Never silently simplify the result or claim to have used a tool you did not use.

An almost-white technical reference page combines delicate mechanical linework, quiet documentation styling, and small warm-toned painted accents. - Color: Off-white background, white cards, pale gray outlines and shadows, charcoal text, muted gray labels, and beige, ochre, and brown painted hands. - Type: Small regular-weight sans-serif navigation and body text, modest headings, monospaced code, and a small italic serif phrase in the footer caption. - Framing: A narrow persistent navigation rail sits left of a central reading column. The large angled watch illustration extends beyond the prose width, with compact controls to its right and generous open space around it. - Structure: Breadcrumb and title; watch illustration with controls and status; explanatory paragraph; rounded command and code cards; theming and standalone usage examples; previous/next links; faded painted-hands image and caption.
