Red line between frame and display of Apple watch SE 40 mm

I just bought Apple watch SE (2nd gen) two days ago, and I noticed that there is red border/line on the watch between the frame and display when seen under sunlight or flashlight.
Is this normal ?
Apple watch se 2 owners can you please check once ?
