Is this a wall clock, table clock or a watch?
(Time...can't tell!) It looks like some kind of a clock because it has no band, no edge buttons (or any apparent way to control/set it), and comes in the clearly square box. However, the simple print on the box lid you can see there...describes it as a 'watch'. Hence the mystery.
Either way, it's a pretty nice classic item, with finger waving Sonic, stars around the edge where the numbers would be & "Segasonic" & "The hedgehog" written around him with a few splats of color.
