Name: Simplicity is Best
Author: Dandelion

AI Tranlated：First , this is my first time making a watch face, and it's purely for my own needs, so I won't be putting too much effort into it.
The face is simple: tick marks and hands, digital time display, and a heart-rate ring. Below I explain two features that are compromises for aesthetics: the heart-rate ring, and the two horizontal lines above and below the digital time.

First, the lines. The top line represents battery level — as the battery decreases, both ends shrink toward the center. The bottom line represents body battery, with the same logic. When the battery percentage drops below 10% or body battery below 15, the entire line turns red.

Now the outer heart‑rate ring:

Ring 1: range 30–90 bpm, changes from gray to blue as heart rate rises.

Ring 2: range 90–150, changes from cyan to green.

Ring 3: range 150–180, changes from yellow to orange.

Ring 4: range 180–210, changes from red to purple (doge).

Rings 1 through 4 are stacked, with Ring 1 at the bottom and Ring 4 on top. The ring changes according to the current heart rate, similar to a tachometer in a car. When the heart rate exceeds the 180 limit, the central time and date disappear, and a red hand creates the atmosphere of approaching the redline (this is not a good thing — try to keep your heart rate moderate).

Simplicity is Best

首先，我是第一次制作表盘，目的是满足自己的需要，所以我并不会投入过多精力。

----表盘很简单：刻度与表针，数字显示，心率环圈。下面解释为美观妥协的两个功能：一个是心率环圈，一个是数字时间的上下两条横线。

----先说横线，上横线代表电池电量，随着电量减少，两端往中间减少；下横线是身体电量，逻辑同上。当电池百分比降至10以下、身体电量15以下时，整条横线变红。

----再说外层心率环圈：第一圈心率范围30-90，随心率上升由灰变蓝；第二圈90-150，由青变绿；第三圈150-180，由黄变橙；第四圈180-210，由红变紫（doge）。

----一至四圈堆叠覆盖，第一圈最下，第四圈最上。环圈会根据当前心率变化，类似机动车转速表。当心率超过180极限时，中间时间与日期会消失，由红色指针来营造逼近红线的氛围感（这不是好事，尽量维持适中的心率）。
