Kimi Open Heart 腕表

Create Kimi Open Heart, a premium interactive 3D product website for a 39.7 mm open-heart mechanical wristwatch. Combine a Cal. 321-inspired column-wheel chronograph movement with a conceptual tourbillon visible through a six-o'clock opening. Use an elegant warm-white studio for most of the experience, with a dark mechanical-heart chapter as a dramatic change of atmosphere. Show polished and brushed steel, engraved silver bridges, circular graining, satin subdials, ruby bearings, a clear sapphire crystal, and carefully controlled warm and cool reflections.

Build a continuous nine-chapter scrolling journey. Begin with a slow orbit and a close-up of the open-heart window. Follow with a six-layer exploded view, a dark particle-and-filament study of the mechanical heart, a three-angle product presentation, an unfolded bracelet, live front-and-back views, a color configurator, a detailed reassembly sequence, and four finish studies at the end. Blend camera position, lighting, background, text, and component motion smoothly between chapters. Scrolling backward should reverse the presentation consistently.

Organize the exploded view into caseback, chronograph, regulation, movement, case, and dial-and-hands layers. Allow hovering to highlight a layer, clicking to isolate and inspect it, and a long press to reveal deeper subassemblies. Show screws, bracelet pins, crown, pushers, bridges, and movement groups separating along plausible directions. Arrange the detached components into an orderly flat lay with related parts together, aligned screws, and coherent bracelet sections. Use 359 visible component units for the detailed assembly, and keep uncertain internal relationships from being presented as verified service instructions. 把腕表替换为一台旁轴胶片相机：保留九章滚动结构、爆炸图与配色定制，章节改为镜头组、快门帘、卷片机构与取景器，配色选项改为黑色、银色与军绿蒙皮。 For reassembly, bring component groups from neatly arranged positions into the watch in a deliberate sequence. Complete rotations before the final straight insertion, keep parts from intersecting, and use a faint transparent outline of the completed watch as a guide. Finish with a close hero view. Animate the balance at 2.5 Hz and the conceptual tourbillon cage at one revolution per minute, with coordinated escapement motion visible in close-ups.

Provide dial choices of ink, blue, and silver; hardware choices of silver, graphite, and champagne; and bracelet choices of silver and graphite. Preserve printed markings, texture, and colored accents when finishes change. Synchronize the chosen configuration across the main watch, front-and-back views, and finish studies. Include Ink Steel, Midnight, Silver Champagne, and Ink Champagne presets that apply the configuration and return to the beginning.

Add an index for all nine chapters, a progress indicator, automatic play and pause, replay, and a return-to-start control. Manual scrolling should take over smoothly from automatic playback. Keep the layout usable on smaller screens, support keyboard access to the configurator, respect reduced-motion preferences, and provide a clear retry option if loading fails.
