This is surprisingly hard. It’s already hard to get an accurate capture of the watch face colors. For some reason if you take a screen capture on your watch the colors will not perfectly match what your eyes are seeing on the device display - perhaps color calibration or brightness effects?
If you have any knowledge on this or would like to suggest a correction, please reach out. The only way I found to go through this is by using the color picker on watch face previews and then eye-balling a correction to brightness and tones so it will look as I wanted.
The color palette is:

The iPhone corrected gradient is: P3: 251,233,204 // 244,174,78
And the gradient wallpaper becomes:
FFA32E -> F0CFAF
