This sounds like a failed backlight in the display. You can check this easily, short press the Digital Crown and side button toy=gether to screenshot the watch. The result should appear in your iPhone photos, if the screen looks normal there it's the backlight.
Try a forced reset (Press and hold the Digital Crown and side button until the Apple appears) to reboot the watch. If that doesn't fix the problem you need help from Apple Support to arrange repair, use link Get Support to start the process.
