智能手表运动环形界面

一张 45mm 圆角方形智能手表 UI 像素级 mockup，纯黑 OLED 屏。屏幕显示户外跑步中：三圈同心活动环（红色 Move 78%、青绿 Exercise 100%、青色 Stand 9/12），下方 2×2 数据网格显示 "4.2 km"、"32:17"、"156 BPM"、"312 kcal"，底部暂停按钮。系统圆角字体，白色数值，灰色标签，红色环光微微映照表盘玻璃。

A pixel-perfect smartwatch UI mockup displayed on a 45mm square watch face with rounded corners and a black OLED background. The screen shows an active outdoor run workout. Three concentric activity rings occupy the center — the outermost ring is vivid red (Move, 78% complete), the middle ring is lime green (Exercise, 100% complete with a small checkmark glyph), the inner ring is cyan (Stand, 9/12 hours). Numerical metrics below the rings are laid out in a 2x2 grid: "4.2 km" (Distance), "32:17" (Time), "156 BPM" (Heart Rate with a small heart icon), "312 kcal" (Active Calories). All text is SF-style rounded system font — metric values in 20px bold white, labels in 11px gray. A tiny pause button (double-circle icon) sits at the bottom center. The watch crown and side button are visible on the right edge of the device frame. Subtle red ambient glow from the ring reflects off the watch face glass.
