Cinematic Watch AI Render Using Seedance 2.5

Create a 15.25-second vertical 9:16 ultra-premium photorealistic CGI luxury-watch product film using the uploaded stainless-steel watch as the strict hero-product reference. Preserve the exact case geometry, integrated stainless-steel bracelet, individual bracelet-link proportions, brushed and polished finishing, circular bezel construction, visible bezel fasteners, silver textured/grid dial, applied hour markers, hour/minute/seconds hands, date aperture on the right side of the dial, crown, crown guards, IWC branding, INGENIEUR dial text, typography placement and every visible product proportion throughout all shots; never redesign, simplify, recolor, distort or substitute any product detail. Render at 25 fps using a virtual full-frame cinematic product camera with approximately 70–120 mm equivalent focal lengths, 1/50 s shutter, ISO 100–200, neutral 5000–5400 K white balance and f/6.3–f/8, physically accurate subtle motion blur and perfectly stabilized robotic movement. Use a seamless charcoal-to-black luxury studio with no visible room, table or props, and keep the visual palette almost entirely monochromatic: stainless steel, silver, neutral gray, white highlights and deep black. Illuminate the watch with one huge diffused rectangular source from upper-left/front, weaker soft front-right fill, strategic black negative fill to sculpt the case and bracelet, and narrow white strip reflections that travel naturally across polished metal while brushed surfaces retain realistic anisotropic texture. From 0–3.52 s, begin with an extreme vertical 100–120 mm macro where the integrated bracelet descends from the top center while only a portion of the dial is initially visible in the lower frame, using a three-quarter front-right orientation with the crown toward frame-right; execute an extremely slow dolly-out and downward reveal so progressively more of the silver dial, bezel, case and crown become visible while the bracelet remains large and tactile, preserving crisp brushed-metal grain, polished chamfers and controlled macro depth of field; by approximately 3–3.52 s reveal almost the complete dial, then hard cut. From 3.52–9.48 s, switch to a dramatically low grazing angle using approximately 90–105 mm where the dial begins strongly foreshortened and almost horizontal with the bracelet extending toward the lower frame; execute one continuous precision camera arc where the camera slowly rises and pitches toward a near-frontal dial view while adding only a very small forward dolly, gradually revealing the full silver textured dial, applied markers, IWC branding, INGENIEUR text, hands, date aperture, bezel fasteners and crown, reducing foreshortening throughout the shot until the dial becomes almost straight-on and fills much of the lower-middle frame around 8–9.48 s; use perfectly smooth ease-in/ease-out robotic movement and never introduce handheld motion. Hard cut at 9.48 s. From 9.48–11.84 s, use an 85–95 mm three-quarter crown-side hero view, positioning the watch diagonally with its dial facing toward camera-left and the crown/case thickness clearly visible at frame-right; perform a very slow dolly-in combined with only a few degrees of orbital adjustment toward a more frontal orientation, emphasizing the difference between satin-brushed surfaces and highly polished bezel/chamfer edges, crown detail and integrated bracelet articulation, keeping the dial and crown sharp while rear bracelet sections fall gently out of focus; hard cut at 11.84 s. From 11.84–14.84 s, show the complete watch centered vertically and almost perfectly frontal using approximately 75–85 mm at f/7.1–f/8, with the entire upper and lower bracelet visible and generous negative space surrounding the product; keep the camera nearly locked with at most an imperceptible 1–2% push-in, allowing only extremely subtle strip-light movement across the steel while maintaining full-product sharpness and exact product geometry. At 14.84 s, hard cut to pure black and show only the authentic centered white IWC wordmark with SCHAFFHAUSEN directly beneath it in smaller lettering, completely static until approximately 15.25 s, then end cleanly. Use hard cuts only around 3.52 s, 9.48 s, 11.84 s and 14.84 s with no dissolves, morphs or flashy transitions. Maintain identical bracelet structure, bezel fastener positions, crown placement, dial typography, date window and case proportions across every angle. Use restrained luxury audio consisting of a deep low ambient tone, extremely soft metallic/precision-mechanical movement, faint servo-like air during the slow camera arcs, subtle cinematic whooshes on cuts and a clean low-frequency resolve before the final IWC card. No dialogue or voiceover. Avoid people, wrists, hands, jewelry boxes, tables, showrooms, props, smoke, particles, colored neon lighting, gold or blue tint, subtitles, UI, watermark, added branding, fake complications, changed typography, incorrect date window, disappearing crown, changing bracelet links, warped circular bezel, missing bezel fasteners, inconsistent dial texture, melting metal, fingerprints, excessive mirror reflections, lens flare, bloom, chromatic aberration, fisheye distortion, wide-angle deformation, handheld shake, fast zooms or random product rotation.
