consumer-quality clocks

I've been delving through product literature on clocks, and this is
what I've found. It looks as if the most accurate clocks that can
affordably be obtained and embedded into devices whose principal
purpose is not precision timekeeping are able on their own to keep
time accurate to about one second per year. Leap seconds currently
happen about once per year. This means that a standalone device
cannot reasonably claim to be keeping either UTC or TAI without
some mechanism for resetting the time.

Does anyone know of affordable clocks which keep time for a year to
an accuracy of better than one second?
