Seems to my untrained eye that the watch could be natural, the pants leg could have buckled right at that point and create the optical illusion that the watch is on top of the pants.
The odd sort of flesh colored object underneath and slightly to the left of Siddiq’s knee with the two intertwined hands could possibly be some other object - can’t think of what, though. If people were going to photoshop this picture (which they did when Siddiq was cut out of it entirely, right?) - they’d get rid of the intertwined hands.
I don’t think the picture was photo shopped. It was in the NYT and they cut Siddiq out of it and photo shopped it.
