Apple Watch bright with Sleep Alarm

Hi,

I have started using the sleep setting on my phone so that I can use the nice sounding alarms like the birds chirping rather than the other ones like radar, lol. I have an Apple Watch and it lays next to my phone in the night stand position so that I can see the time. I actually really like this because even if there’s a slight movement it turns on which is super cool briefly so I can see the time. To add a few more details I know that if you wear the watch it’ll go off on the watch and tap your wrist and I believe it goes off on the phone too. Because im not wearing the watch it only goes off on my phone which I also really like. Recently, I have noticed that if I have the sleep alarm set for 6am or something I will wake up right before at like 5:57 because the watch which is right next to my head has turned on as bright as possible and is shinning the time in the horrible green color. It’s really weird but for some reason the watch just turns on super bright a few minutes before the alarm which isn’t really very pleasant. It kinda ruins the gradual sounding alarm. Does anyone know how to make the watch not turn on super bright like that? I want to make sure I don’t change a setting to make the alarm go off on the watch too because I like it only going off on my phone. If anyone has an ideas let me know!
