Here is a plastic edge wall clock with Sonic, Tails & Knuckles theme. It has red hands & a black second hand. The numbers are white, while the background is sort of abstract streaky/clouds.
Generally: BEWARE of wall clocks
This one is in the original package, so it is highly likely to be official, but such clocks are extremely easy to fake. Stealing some art & making a cardboard disk is about all it takes to fake up a clock, so beware of bootlegs & only buy stuff that's in a package (like this one) with proper copyrights & from a source that seems reputable.
