Watch face distorts as second hand passes 3 o’clock

Hi there

first time in here. Just bought a 5x and after set up I notice The Watch face distorts as second hand passes 3 o’clock, every time, regardless of which watch face is on. See image  I updated the software to the newest version, tried a factory reset. has anyone seen this before?  I can see nothing like it on searching online.  

I can return the watch but I got it at such a good price I’d like to fix it!
