The quartz movement works at such a fast rate of vibration (Hz) that a variation in manufacturing will not affect the percentage of accuracy to any great extent. They also use very little power excluding the displays power consumption.
So I guess the answer comes down to cost, familiarization with manufacturing methods, and cost.
I know nothing about computers.
Well, what about cell phones? They don't have movements in them. Mine is always accurate. I ask this question precisely because I am not an expert on either computers or quartz movements, so I was just wondering if there is an easy explanation. I mean, if you wrote a program that covered every second of every day in every year in a four-year sequence (to account for leap years) and timed it out to exactly how many seconds that is, then setting the watch would just be a matter of adjusting one's position on the calendar and counting down, chronograph style -- much as a DVD player counts down the seconds of a movie -- not a process of counting forward indeterminably. When you play a DVD, the DVD player can't ever be "wrong" in its countdown, so I'm just wondering why digital timepieces can't/don't work by this same principle. (obviously, I'm not doing anything particularly important at work today).
