Create a high-end product photography image of a luxury watch, featuring a sleek, modern design. The watch should be positioned on a reflective surface in a studio setting, with soft, diffused lighting that creates a gentle glow around the watch. Focus on the intricate details of the watch face, including the luminous markers and the texture of the strap. The background should be a soft gradient that complements the watch's color palette, enhancing its luxurious appeal while keeping the focus on the timepiece.
