ไทม์ไลน์การประกอบผลิตภัณฑ์อุตสาหกรรม 5 ขั้นตอน

5-stage horizontal manufacturing timeline of [a sleek mechanical wristwatch], frozen mid-assembly against a deep matte black background with dramatic industrial spotlights and deep shadow falloff. Stage 1: Components scattered and floating, zero assembly. Stage 2: Converging with speed lines, internal skeleton emerging. Stage 3: Half-built under peak tension, fasteners mid-tighten. Stage 4: Chassis open with full internals exposed. Stage 5: Finished assembled product with a ghost wireframe overlay. Consistent 3/4 camera angle across all five stages, connected by dotted trajectory arcs tracking each component, with consistent color coding.
