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.
