One of the jibes occasionally tossed at quartz watches by spring chauvinists is that the seconds hand moves in one second ticks and (in many cases) doesn't line up with the dial markings.
Let's forget that the one second ticks thing was an expensive complication in mechanical watches (oh for a Milgauss tru-beat) how about the lining up?
One of the causes of apparent misalignment is the dial and hands not being truly concentric. I reckon that a great number of watches are like this - mechanical and quartz. I reckon, also, that the stepping of a quartz seconds hand makes this misalignment more obvious. The smaller steps of a mechanical watches seconds hand will cause it to appear to pass over each of the marks on the dial and I think that the instantaneous position of the hand relative to these marks is the cue that people use to "see" misalignment. Seeing the misalignment in a mechanical watch would require a fifteen or twenty second image memory.
Any opinions on this?
