带蓝宝石玻璃与拆解功能的交互式3D机械腕表

Use Three.js to develop a highly faithful 3D interactive watch model of an IWC Schaffhausen timepiece. Requirements: 1) The dial structure must be highly precise, with every mechanical component individually rendered and clearly distinguishable; 2) The watch face must use a sapphire glass material with realistic transparency, refraction, and reflection effects; 3) The minute hand and second hand must be correct hands that follow real timekeeping logic, with automatic continuous hand-sweep animation; 4) Support disassembly and reassembly of the watch, with each part able to be separated and viewed individually; 5) The overall level of detail must be extremely high, closely matching the structure and proportions of a real watch, with realistic material textures for screws, metal parts, and other components, and fine craftsmanship. Please ensure the model runs smoothly in the browser and interacts naturally.
