Mechanical Watch Movement

Original prompt

Create a standalone animated SVG showing a transparent mechanical wristwatch movement.

It should include:
- hour, minute, and second hands
- multiple interlocking gears
- an escapement mechanism
- an oscillating balance wheel
- a mainspring or power source
- realistic relative rotation directions between connected gears
- different gear rotation speeds
- pause/resume controls
- a speed control

The mechanisms must behave as a coherent system rather than as unrelated decorative animations.

Do not use external assets.

Chinese translation

创建一个独立的动画 SVG，以透明机械腕表机芯为主题。它应包含时针、分针、秒针，多组相互啮合的齿轮，擒纵机构，往复摆动的摆轮，以及发条或其他动力来源。相互连接的齿轮应具有合理的相对旋转方向和不同转速，并提供暂停/继续与速度控制。机械机构必须作为统一系统运行，而不是彼此无关的装饰动画。不得使用外部资源。

Expected outcome

The deliverable should be a polished mechanical-watch SVG animation with coherent transmission behavior. Meshing gears should rotate in opposite directions at sensible relative speeds, the three hands should maintain realistic speed ratios, and the balance wheel plus escapement should visibly behave as linked mechanisms. Pause/resume and speed control should preserve the mechanism's phase.

Additional verification guidance

• Verify that directly meshing gears rotate in opposite directions and do not visibly intersect, detach, or spin independently.
• Compare relative speeds of hands and gears and confirm there are no obvious errors such as all elements rotating at the same rate.
• Confirm that the balance wheel oscillates, the escapement visibly relates to that rhythm, and pause/resume or speed changes do not corrupt phase.
• Validate offline operation, SVG syntax, crisp scaling, controls, and overall technical-illustration quality.
