Luxury Spherical Sapphire Watch

Generate a hyper-realistic image of a luxurious, intricately designed spherical watch adorned with large, deep blue sapphires and clear gemstones, set in a gold framework. The watch face features an ornate, filigree-style design with Roman numerals and is positioned centrally within the sphere. The sphere is illuminated from below, casting a warm glow on the surrounding dark surface. The background transitions from dark blue at the top to a gradient of purple, pink, and orange hues towards the bottom, creating a dramatic and opulent atmosphere. The overall composition should evoke a sense of high-end jewelry or a luxury timepiece advertisement, with meticulous attention to detail in the rendering of textures, reflections, and lighting. The image should be devoid of any watermarks or logos and should resemble a high-end design editorial or campaign photograph.
