Draw a mechanical wristwatch that shows the current local time, with a sweeping seconds hand and a date window. Make it look expensive.

It must be one complete, self-contained HTML file: inline all CSS and JavaScript, and make no network requests of any kind (no CDNs, web fonts or remote images). Save it as index.html in the current directory, then stop. Do not ask questions.
