The problem is the human visual system only processes one object at a time. You can't look at and compare two separate items simultaneously. You could minimize the effect by placing one clock face directly in front of the other with like only the 12:00 positions visible (or two LEDs next to each other). That way the two second hands can be perceived simultaneously.
