Vintage Pocket Watch Cityscape

Create an image depicting a vintage pocket watch suspended in mid-air, with a miniature city inside its case where time flows differently across various districts. Skyscrapers dynamically rise and fall, mimicking tidal rhythms. Vividly colorful birds flutter across the sky, leaving radiant traces of light. Luminescent gears encircle the pocket watch, glowing with a golden haze and reflecting the four seasons' rhythm in a hypnotic dance. The image should be a meticulously detailed matte painting with rich, deep colors, evoking a sense of fantasy. The style should be reminiscent of high-quality concept art found on platforms like Artstation and Unreal Engine.
