Either way, the difference is within the limits of the basic tin wind-up
alarm clock.  A quality wrist watch would not work because it is to good
and harder to adjust.  Something like this:
Westclox-15396-Ardmore-Twin-Bell<http://www.amazon.com/Westclox-15396-Ardmore-Twin-Bell/dp/B0000V0DEW/ref=pd_sim_hg_1>

Now if the OP wants to track apparent solar time to better then a few
seconds per month, then it gets real hard if you have to do it with
springs, pendulums and gears because the clock needs to track the date.  I
think you might need some kind of of non-round cam that revolves once per
year.

But if you are willing to set the clock about once a week a cheap wind-up
clock would be good enough to tell visually you when the sun is at local
noon to within a minute or so.
