There is an unusual yellow frame around the watch face - which isn't part of the pixels on the screen itself but wrapping around it that is yellowish in tint when viewing the watch in bright daylight. It's hard to imagine that this is part of the display, that it is visible or it's the cellular antenna. One could imagine the Apple doesn't want you to see this.
A friend claims to not see this on their Apple Watch Series 3.
So what is it? Do others see it as well?
Apple wants to send it in for repairs and if it is a manufacturing defect I'll be really a bit pissed off if I get a refurbished watch. Screw that!
Apple support has seen the same screen image.
