博物馆风格物品结构技术信息图

设计一张方形白色影棚信息图，以黑色技术笔标注、均衡留白，并在角落设置一个小标题框；主题是一只表壳、表盘、指针、表冠和表带均清晰可见的经典机械腕表。将完整腕表以光线充足、真实的四分之三角度产品视图呈现为明确主体，叠加黑色墨线技术草图与建筑制图风格标注，但不要遮挡腕表。加入少量可见部件标签、简洁的黑色引线和箭头；只有在能够合理呈现时才加入示意剖面。标签仅简短描述可见或已有明确依据的特征；比例刻度仅作示意且不标数值，不要虚构尺寸、数量、材质或隐藏的内部结构。在角落附近用手绘小方框标出物品名称。线条清晰而略带手绘感，标签简洁易读，整体层级平静、具有教育性，类似博物馆展览或工程手册。物品只呈现自身灰度，画面仅使用白色、黑色和灰度；不要装饰色、水印或无关文案。

【English Prompt】
Design a square white studio infographic with black technical-pen annotations, balanced negative space, and a small boxed title in one corner, about a classic mechanical wristwatch with its case, dial, hands, crown, and strap clearly visible. Present a realistic, well-lit three-quarter product view that keeps the complete object unobstructed as the unmistakable focal point, with black-ink technical and architectural sketch annotations overlaid without hiding it. Include sparse labels for visible parts, simple black leader lines and arrows, and an illustrative section view only where it can be shown coherently. Use short descriptive labels only for visible or clearly established features; use schematic, non-numeric scale marks and do not invent dimensions, quantities, materials, or hidden internals. Put the object title in a small hand-drawn box near one corner. Keep linework crisp but lightly hand-drawn, labels concise and legible, and the overall hierarchy calm and educational, like a museum exhibit or engineering manual. Use only white, black, and grayscale object tones; no decorative color, watermark, or unrelated copy.
